A.2 SPECIFICATIONS
VOLUTE: The volute is top centerline with a fully confined gasket. The foot support is used for maxi-
mum resistance to misalignment and distortion from piping loads.
However it is important not to impart piping loads on to the pump.
IMPELLER: The impeller is fully open and threaded to the shaft. The threads are sealed by a Teflon
O- ring.
Never rotate the pump counter clockwise as the impeller can unscrew and rub on the casing.
STUFFING BOX COVER: Machined for mechanical seal or conventional packing.
FRAME ADAPTER:The ductile iron frame adapter has a machined rabbet fit to the seal chamber /
stuffing box cover and a precision dowel pin fit to the bearing frame.
BEARING FRAME: Of rigid iron construction. No machining is required to convert from oil to grease or
oil mist lubrication. Flood oil lubrication is standard. The oil level is viewed through a sight glass. The
power end is sealed with an Inpro “VBX” labyrinth seal.
SHAFT: Manufactured from 4140 steel with an adjustable bearing and a bolt type roll pin on the shaft
end. The 316SS shaft (also available) does not require a sleeve.
BEARING SUPPORT: Is Constructed of ductile iron, it is rigid and has grooves and openings for oil
lubrication, grease or oil mist.
OUTBOARD BEARING: Angularly locked and connected to the shaft and housing to ideal with thrust
loads.
INBOARD BEARING: Its rigid, simple design, adequate for high RPM, also requires little attention in
service.
NAMEPLATE INFORMATION: Each pump has a nameplate that provides information about the
pump, such as pump model, size impeller diameter, construction material, serial number, etc., (Fig 1).
The nameplate is located on the bearing frame. When ordering spare parts you will need to identify
pump model, size, serial number and the item number of required parts.

A.3 RECEIVING AND INSPECTING THE PUMP
Please inspect the pump as soon as it is received and check that everything is in order. File any claims
with the transportation company. This is a weighty pump; lifting equipment must be able to adequately
support the entire assembly (Fig 2, 3).
DANGER
STORAGE REQUIREMENTS
Proper storage of your MAGNATEX pump will insure that it is ready for service when needed.
GENERAL RULE: Pumps with corrosive fluid application; the process side of the pump should be drained
and flushed with water and blown dry using low pressure air flow. After pump is dry a suitable rust
preventative should be applied to the interior of the process side of the pump, whenever idle for periods
in excess of (1) month or less for humid environments.
For oil lubricated pumps the used oil should be drained and the reservoir filled with fresh oil to the nor-
mal operating level. Pumps with sealed grease-lubricated bearings do not require any special attention.
SHORT TERM STORAGE: No special steps are required if the pump is stored indoors in a temperature
controlled environment, for less that (6) months. Follow general rule, and rotate the pump shaft several
times every 3 months.
LONG TERM STORAGE: In excess of (6) months, all machined surfaces and bearing must be treated with a
rust preservative. Rotation of the shaft will be required every 3 months. Refer to coupling and driver
manufacturer to comply with their recommended long term storage procedures. Unit must be stored in
a covered and dry location. For specific recommendations regarding your storage conditions contact
MAGNATEX Pumps.

SECTION B
PUMP INSTALLATION
A pump should be located near the supply of liquid and have adequate space for operation, maintenance
and inspection.
B.1 FOUNDATION AND BASEPLATE ALIGNMENT
FOUNDATION
Baseplate mounted pumps are normally grouted on a concrete foundation, which has been poured on a
solid footing; foundation bolts commonly used are J – type and sleeve – type. Both designs permit
movement for final bolt adjustment.

5
3575 IOM R6
LEVEL BASEPLATE
A. Place one set of wedges or shims on each side of every foundation bolt. The wedges should
extend between ¾” and 1 ½” above foundation to allow for adequate grouting.
B. Remove liquid and / or debris from anchor bolt holes/sleeve before grouting. If the sleeve type
bolts are being used, fill the sleeves with packing or rags to prevent grout from entering.
C. Lower Baseplate on to foundation bolts.
D. Level Baseplate to within 1/8” over length of the Baseplate and to within 1/16” over the width
of the base by adjusting the wedges.
E. Hand tighten the bolts.

3575 IOM R6
B.2 ALIGNMENT
INITIAL ALIGNMENT CHECKS: (Done prior to operation)
Check before grouting the Baseplate to be sure correct alignment is possible.
Check after Baseplate is grouted to see if grouting process has altered alignment.
After pipes are connected, check to see if strained connections have altered alignment. If so,
eliminate piping strain to achieve optimal alignment.
FINAL ALIGNMENT:
Alignment should be checked after first run when both pump and driver are at operating
temperature.
Alignment should be checked periodically in accordance with plant operating procedures.
Good alignment should be checked periodically in accordance with plant operating procedures.
Good alignment is achieved when the dial indicator readings are 0.002 in or less.

PREPARATION FOR START‐UP
DANGER
Make sure driver power is locked out.
Failure to lock out driver power may result in serious physical injury.
C.1 ROTATION CHECK
CAUTION
Serious damage may result if pump is run in the wrong rotation.
1. Make sure spacer element is removed from the coupling hubs and that the hubs are securely
fastened to shafts.
2. Connect driver power and JOG driver just long enough to determine direction of rotation.
Rotation must correspond to arrow on bearing housing.
3. Open disconnect for driver power source.
4. Re-connect coupling halves with spacer coupling element and re-install coupling guard.
C.2 CHECK IMPELLER CLEARANCE
Before starting the pump the impeller clearance must be checked. The pump efficiency is maintained
when the proper impeller clearance is set. Impeller front clearance is factory set to predetermined
limits.
Minimum values for different temperatures appear in the following table. The impeller clearance
adjustments are necessary to prevent the impeller from contacting the casing due to differential
expansion at higher operating temperatures. See section I.2 for impeller clearance setting.

START‐UP D.1
CAUTION
Pump has been shipped without oil in the bearing housing
in compliance with US DOT regulat ions.
Add oil to the bearing housing (oil lubricated pumps only!) prior to operation.
Serious damage may result if pump is run without adequate lubrication.
LUBRICATION
Bearing lubrication is very important for the best service life of the pump. Regular oil changes
and lubrication analysis is part of the best maintenance practices for optimum reliability. As
operating conditions vary frequency of re-lubrication can be modified based upon operating
records for the specific pump service.
Recommended lubricants:
OIL: ISO VG68 High Quality turbine oil. Maintain oil temperature
between 122°F (50°C) and 180°F (82°C) for normal operation. For
operation with pumped liquids above 350°F (177°C) use finned oil
cooler. Contact Magnatex Pumps Inc. with any questions.
Suitable oil brands:
Shell – Tellus Oil 68 Royal Purple – SYNFILM VG68 Synth.
Chevron – GTS Oil 68 Exxon – Terrestic EP 68
GREASE: NLGI No.2, sodium or lithium based. Approximate volume of grease per bearing in cubic
centimeters: 1-2 cc for 3575S; 2-3 cc for 3575M/L; and 3-4 cc for 3575XL.
Suitable grease brands:
Exxon Mobil – Mobil Polyrex EM Shell – Shell Dolium R
Chevron – Chevron SRI Exxon Mobil – Mobillith SHC 100
STARTING PUMP
1. Add oil to pump bearing housing via breather port (breather must be removed) until level shows
in the sight glass at the middle of the gauge window. Allow the level to settle out before adding
additional oil. Do not overfill!
2. Ensure that suction valve and any recirculation or cooling lines have been opened.
3. Completely close or partially open discharge valve as determined by system conditions. Never
open discharge valve more than 25% on startup.
4. Start driver. Observe pressure gauges. Stop driver if discharge pressure is not attained quickly.
Allow about 10 seconds for the system liquid levels to settle and attempt to re-start. If pump still
does not come up to pressure, vent all high point vents, re-prime pump and attempt to restart.
5. Open discharge valve slowly until the desired flow is obtained. If normal levels of vibration,
bearing temperature and noise are exceeded, shut the pump down and resolve the problems.

9
3575 IOM R6
6. To prevent damage resulting from cavitation or recirculation always operate the pump at or
near the rated conditions.
7. If the specific gravity is greater than originally assumed or the rated flow rate is exceeded the
driver could overload. The following table shows minimum recommended flows.
8. Always change capacity by regulating the valve in the discharge line. Never throttle flow from
the suction side, which can cause cavitation and serious damage to the pump.
D.2 OPERATING MAGNATEX 3575 PUMP AT REDUCED CAPACITY
CAUTION
Do not operate pump below minimum rated flows or with suction and/or discharge valve
closed. These conditions could cause an explosive hazard due to vaporization of pumped liquid
and can rapidly lead to pump failure and physical injury.
