Care of Stainless Steel Waukesha Cherry-Burrell
Page 8 95-03092 November 2009
Care of Stainless Steel
Stainless Steel Corrosion
Corrosion resistance is greatest when a layer of oxide film is formed on the surface of stainless steel. If film is
disturbed or destroyed, stainless steel becomes much less resistant to corrosion and may rust, pit or crack.
Corrosion pitting, rusting and stress cracks may occur due to chemical attack. Use only cleaning chemicals
specified by a reputable chemical manufacturer for use with 300 series stainless steel. Do not use excessive
concentrations, temperatures or exposure times. Avoid contact with highly corrosive acids such as
hydrofluoric, hydrochloric or sulfuric. Also avoid prolonged contact with chloride-containing chemicals,
especially in presence of acid. If chlorine-based sanitizers are used, such as sodium hypochlorite (bleach), do
not exceed concentrations of 150 ppm available chlorine, do not exceed contact time of 20 minutes, and do not
exceed temperatures of 104°F (40°C).
Corrosion discoloration, deposits or pitting may occur under product deposits or under gaskets. Keep surfaces
clean, including those under gaskets or in grooves or tight corners. Clean immediately after use. Do not allow
equipment to set idle, exposed to air with accumulated foreign material on the surface.
Corrosion pitting may occur when stray electricalcurrents come in contact with moist stainless steel. Ensure all
electrical devices connected to the equipment are correctly grounded.
Alloy 88
Waukesha Alloy 88 is the standard rotor material for Universal I, Universal II, Universal Lobe, Universal 420/
520 and 5000 Series Rotary PD pumps. This alloy was developed specifically for corrosion resistance and
close operating clearance requirements of high performance rotary positive displacement pumps. Alloy 88 is a
nickel-based, corrosion-resistant, non-galling or seizing material. The ASTM designation is A494 Grade
CY5SnBiM (UNS N26055), and the material is listed in the 3-A Sanitary Standards as acceptable for product
contact surfaces.
The above properties make Alloy 88 the ideal material forWaukesha stainless steel PD pumps. The non-
galling rotors permit close operating clearances in the liquid end. This provides low slip and minimum shear
damage. The rotors will not gall or seize if they come in contact with the body or cover during operation.
The corrosion resistance of Alloy 88 is approximately equal to AISI 300 Series Stainless Steel. However, Alloy
88 has limited resistance to certain aggressive chemicals that may be commonly used in contact with AISI 300
Series Stainless Steel.
Do not use Alloy 88 in contact with nitric acid. Nitric acid is commonly used to passivate new installations of
stainless steel equipment. Do not allow nitric acid based passivation chemicals to contact Alloy 88 rotors.
Remove the rotors during passivation and use a separate pump to circulate the passivation chemicals. Also, if
nitric acid-based CIP cleaning chemicals are used, remove the rotors prior to CIP cleaning and clean them
separately by hand in a mild detergent.
If you have questions regarding other aggressive chemicals, please contact Waukesha Cherry-Burrell
Application Engineering for assistance.
Elastomer Seal Replacement Following Passivation
Passivation chemicals can damage product contact areas of WCB equipment. Elastomers (rubber
components) are most likely to be affected. Always inspect all elastomer seals after passivation is completed.
Replace any seals showing signs of chemical attack. Indications may include swelling, cracks, loss of elasticity
or any other noticeable changes when compared with new components.

Waukesha Cherry-Burrell Introduction

Introduction
Pump Receiving
DANGER: The pump contains
internal moving parts. DO NOT
put hands or fingers into the pump
body ports or drive area at any
time during operation. To avoid
serious injury, DO NOT install,
clean, service, or repair the pump
unless all power is off and locked
out.
All ports are covered at the factory to keep out foreign objects
during transit. If covers are missing or damaged, remove the
pump cover and thoroughly inspect the fluid head. Be sure the
pumping head is clean and free of foreign material before rotating
the shaft.
Each Waukesha Cherry-Burrell pump is shipped completely
assembled,lubricated and ready for use. Review “Operation” on
page 17 before operating the pump.
Pump Characteristics Waukesha Cherry-Burrell Universal Lobe pumps are positive-
displacement, low-slip, stainless steel pumps designed with
larger diameter shafts for greater strength and stiffness, mounted
on a heavy-duty cast iron bearing frame (stainless steel option
available) with double-tapered roller bearings.
• Designed for continuous operation.
• Rotor hubs are sealed from the product zone; rotors are
locked with belleville-style washers and torqued nuts that can
rotate securely in either direction (bi-directional).
• Non-galling “88” alloy rotors are standard; 316 material rotors
are optional.
• Seal flush is standard. Seal areas are interconnected to
improve circulation and draining of the seal flush fluid.
• Single mechanical seals are standard. Bodies are pre-drilled
with flush ports if double seals are required.
• Free-draining pump body and cover when mounted on its
side.
• CIP capability is standard.
Equipment Serial Number All Waukesha Cherry-Burrell pumps are identified by a serial
number on the gear case nameplate, which is stamped on the
pump body and cover.
CAUTION: The gear case, body, and cover must be kept
together as a unit due to backface, rotor and cover
clearances. Failure to do so will damage the pump.
Pump Shaft Location There are two pump drive shaft locations.

Installation Waukesha Cherry-Burrell
Page 10 95-03092 November 2009
Installation
Install the pump and piping system in accordance with local
codes and restrictions. Practices described in this manual are
recommended for optimum performance.
All system equipment, such as motors, sheaves, drive couplings,
speed reducers, etc., must be properly sized to ensure
satisfactory operation of your Waukesha Cherry-Burrell pump
within its limits.
CAUTION: These pumps are positive displacement, low-
slip design and will be severely damaged if operated with
closed valves in the discharge or inlet lines. The pump
warranty is not valid for damages caused by a hydraulic
overload from operation or start-up with a closed valve in
the system.
Install Pump and Drive
Unit
WARNING: Full guards must be installed to isolate
operators and maintenance personnel from the rotating
components. Guards are provided with Waukesha Cherry-
Burrell pumps as part of a complete pump and drive
package.
In a typical installation configuration, the pump and drive unit are
mounted on a common base plate. The unit can be installed in
any of the arrangements shown in Figure 3 through Figure 6 (the
shaded area indicates the guard location).
NOTE: When installing unit as shown in Figure 6, level the unit
before installing the bolts.

Install Connections and
Piping
Fittings
Waukesha Cherry-Burrell produces a wide variety of fittings
made to meet your needs. Contact Waukesha Cherry-Burrell
Customer Service at 1-800-252-5200 or 262-728-1900 for
information on fittings.
Piping Support
Support all piping to the pump independently with hangers or
pedestals to minimize the forces exerted on the pump. Such
forces can cause misalignment of pump parts and lead to
excessive wear of rotors, bearings and shafts.
Figure 7 shows typical supporting methods used to independently
support each pipe, reducing the weighteffect of piping and fluid
on the pump.
Expansion Joints
Thermal expansion of piping can cause tremendous forces. Use
thermal expansion joints to minimize these forces on the pump.
Flexible joints can be used to limit transmission of mechanical
vibration. Ensure that the free ends of any flexible connections in
the system are anchored.
Inlet Piping
Install the pump below the supply liquid level to reduce air in the
system by flooded suction (Figure 9).
If the pump is installed above the supply liquid level, the piping on
the inlet side must slope up toward the pump, preventing air
pockets in the pipes (Figure 10).

Installation Waukesha Cherry-Burrell
Page 12 95-03092 November 2009
Install Check Valves Inlet Side on Lift Applications
Use check valves to keep the inletline full, particularly with low-
viscosity fluids (Figure 11).
Discharge Side
For systems with liquid under a vacuum, install a check valve on
the discharge side of the pump. A check valve prevents backflow
(air or fluid) to aid in initial start-up by minimizing the required
differential pressure supplied by the pump to start the flow (Figure
12).
Install Isolation Valves
Isolation valves permit pump maintenance and safe pump
removal without draining the system (Figure 13, item A).
Install Relief Valves Install relief valves to protect the pump and piping system against
excessive pressure. WCB recommends installing an external
relief valve, designed to bypass fluid from the pump outlet to the
inlet side of system (Figure 14, item A).
NOTE: Integral relief valves are available, but are not
recommended on applications with viscosities over 500 cps or
where the discharge must be closed for more than a few minutes.
Prolonged operation of the pump with closed discharge will cause
heating of fluid circulating through the relief valve. If this is the
case, install an external relief valve to discharge externally
through the piping connected to the fluid source, or into inlet
piping near the source.

Inlet Side Strainers and
Traps
Inlet side strainers and traps (Figure 15, items A and B) can be
used to prevent foreign matter from damaging the pump. Make
the selection carefully to prevent cavitation caused by the
restriction of the inlet. If the inlet strainers are used, they must be
serviced regularly to prevent clogging and flow stoppage.
Install Pressure Gauges
Pressure and vacuum gauges provide valuable information about
pump operation (Figure 16). Wherever possible, install gauges to
help provide information on the following:
• Normal or abnormal pressures
• Indication of flow
• Changes in pump condition
• Changes in system conditions
• Changes in fluid viscosity
Seal Flush Connections Pumps with double seals require flushing. The flush media
(typically water) must be connected and flowing whenever pump
is operated.
WARNING: Operating the pump without flush will damage
the seal and pump parts due to excess heat from dry
running.
Pump bodies have two 1/8-inch female pipe thread flush
connections located near bottom and top of body.
1. Connect the flush inlet to the lower connection, and the outlet
to the upper connection, to flood the flush area completely.
2. Connect the flush outlet for unrestricted flow to the drain.
NOTE: If steam is usedas flush media, connect the inlet at the
upper connection and the outlet at the lower connection, to
ensure condensation removal.
3. Use cool, filtered flush media to obtain maximum service life
of the seal components. If the pumped product is sticky or
solidifies at room temperature, use warm or hot flush media.
4. Install a pressure reducing valve and flow control valve
(needle valve) on the flush supply line. Set the supply
pressure at a maximum of 30 psi (2 bar) and adjust the flow
rate to approximately 1/4 gpm (more for high-temperature
applications).

5. Also install a solenoid valve in the flush supply and wire it in
series with the motor starter to provide an automatic start/
stop of the flush media flow before the motor turns on and
after the motor turns off.
NOTE: If the pumped product contains abrasive solids or
hardens on the seal faces, an alternate high pressure barrier
flush arrangement may be used. A very small amount of flush
liquid enters the pumped liquid, therefore the flush media must be
compatible with the product. Contact WCB Application
Engineering for assistance.
CIP (Clean-In-Place)
Features
WCB UL pumps are designed to provide CIP solutions complete
access to all product contact surfaces. The flat body profile
allows complete draining of the side-mounted pump, and
provides the CIP solution access to the entire cover o-ring
groove.
Use the following guidelines when designing and installing the
CIP system to ensure successful cleaning:
• Ensure that the velocity rate of CIP solutions is adequate to
clean the entire circuit. For most applications, a velocity of 5
ft/sec is sufficient. For the CIP solution to achieve the proper
velocity, the pump drive must have enough speed range and
horsepower. The required inlet pressure also must be
satisfied. If the pump does not supply enough CIP solution
velocity, a separate CIP supply pump with an installed
bypass may be used. To determine the appropriate bypass
arrangement, contact WCB Application Engineering.
• Ensure that a differential pressure is created across the
pump. Differential pressure will push CIP solutions through
close-clearance areas of the pump, resulting in better
cleaning action. The high pressure side may be either the
inlet or outlet side. 30 psi (2 bar) differential pressure is
adequate for most applications.
• The pump must be operated during CIP to increase
turbulence and cleaning action within the pump. If complete
draining is required, the pump must be in the side mount
position.

Waukesha Cherry-Burrell Installation
November 2009 95-03092 Page 15
Check Coupling Alignment
Pumps and drives ordered from the factory and mounted on a
common base plate are aligned before shipment. Alignment
must be re-checked after the complete unit has been installed
and piping completed. Periodic re-checking is advisable during
the pump service life.
• WCB recommends using a flexible coupling to connect the
drive to the pump. Several different types are available,
including couplings with slip or overload provisions.
Waukesha Cherry-Burrell provides Lovejoy (Figure 18) or
T.B. Woods®(Figure 19) couplings unless otherwise
specified when ordering. Flexible couplings can be used to
compensate for end play and small differences in alignment.
• Align the pump and drive shaft as closely as possible:
Pump and Drive are factory aligned.
Re-check alignment after installation and before start-up.
Re-check alignment periodically, to maximize service life.
Check Angular Alignment
1. Using feeler gauges or taper gauges (Figure 20, items A and
B), check the alignment at four points every 90 degrees
around the coupling; adjust to equal dimension at all
points.
2. Set the space between the coupling halves to the
manufacturer’s recommended distance.
3. Install shims to bring the system into alignment.
Check Parallel Alignment
1. Check both the horizontal and vertical alignment of the pump
and drive using a straight edge.
2. Using a feeler gauge at location “A” in Figure 21, determine
the direction and amount of movement needed (Figure 21,
item B).
3. If necessary, shim at location "C" and/or move the drive as
needed.

Check Belt and Chain
Drive Alignment
Use a straight edge to visually check the belt or chain alignment.
Keep the shaft distance to a minimum (Figure 22, item A).
After the piping is complete and before the belts are installed,
manually turn the pump shaft to ensure that it turns freely.
Check Pump Rotation Check the direction of the drive rotation to determine the rotation
direction of the pump (Figure 23). After the correct drive rotation
is verified, connect the coupling and assemble the pump and
coupling guards.
NOTE: The pump covers in the following figures have been
removed to view rotor rotation. Never operate the pump with the
covers removed.

Gears are factory-lubricated with gear oil at the quantity shown in
Table 2. Change the oil every 500 hours.
Gear Oil Specification
ISO Grade 320, SAE 140 or AGMA Number 6EP.
Bearings
Bearings are factory-lubricated with grease. Re-grease them at
the quantity shown in Table 2. Grease the bearings every 250
hours.
Excess grease will accumulate in the gear case and must be
removed through the cleanout hole covered with a plastic plug
(Figure 24, item 48).
Bearing Lubricant Grease
NLGI Grade No. 2, EP, Lithium-based lubricant is standard.

Maintenance Inspections DANGER: The pump contains internal moving parts. DO
NOT put hands or fingers into the pump body ports or drive
area at any time during operation. To avoid serious injury,
DO NOT install, clean, service or repair the pump unless all
power is off and locked out.
Detecting wear in the early stages can reduce repair costs and
down time. A simple “look-feel” inspection of the pump during
breakdown cleaning is recommended to detect signs of trouble at
an early stage.
A detailed maintenance inspection should be scheduled annually.
See “Annual Maintenance” on page 22.
Refer to the “Maintenance Inspection Chart” on page 21 for
possible causes and solutions to common issues discovered
during inspection.
Inspection of Rotor Tips
Remove the cover (see “Remove Cover” on page 23) and check
for metal-to-metal contact between the rotor wings. When contact
is detected, repair or replace the pump.
Visually inspect the rotors for rotor-to-rotor contact and rotor-to-
body contact. Manually rotate the pump drive shaft and ensure
that the rotor-to-rotor clearance is equal on both sides as
indicated in Figure 25. If contact occurs, see “Checking for Proper
Clearance” on page 39 for proper clearances.
Inspection of Rotor and Shaft Spline
Visually inspect the rotor and shaft spline (Figure 26) for
excessive wear; replace as necessary.
Inspection of Shaft
Visually inspect the shaft for twists or bends; replace it as
necessary.
Inspection of Rotor Hub End
Visually inspect the rotor hub end (Figure 26, item A) for
excessive wear; replace it as necessary. Each time rotors are
removed, replace the o-rings on the hub.

Inspection of Shaft Shoulder
Visually inspect the shaft shoulder (Figure 27, item A) for
excessive wear; replace it as necessary. If the shaft shoulder has
a sharp edge, remove the edge with a file to prevent cutting the
shaft o-ring on installation.
NOTE: Rotor hub and shaft shoulder wear are caused by
operating with a loose rotor nut(s) for extended periods.
Inspection of Gears and Bearings
Gear backlash
With the fluid head and seals removed, feel for gear backlash by
rotating either shaft by hand. The other shaft must engage
immediately. Perform this check three times at 60-degree
intervals. If play (backlash) is evident, remove the gear case
cover, check the gear teeth for wear, and ensure that the gear is
not loose on the shaft. If the gear teeth are worn, replace the
gears. If the gear is loose on the shaft, inspect the shaft key and
keyway; replace as necessary.
Check bearing condition
With the fluid head and seals removed, check the bearing
condition by applying (by hand) an up or down force of
approximately 30 lbs (14 kg). If movement of either shaft can be
detected, the bearing may be failing. Also check the shaft
movement forward or backward. If the bearing is failing, replace
the bearing and review the lubrication section on page 18.
