3.0 Installation
Ensure that all regional and industry specific safety standards and procedures are understood
and followed prior to and during the installation process. All electrical work must be performed
by a certified electrician.
3.1 Pump Mounting and Positioning
The pumps can be directly mounted on the sump floor supported entirely by the pump stand.
The sump floor must be level to prevent the pump from tipping over during operation. If the
sump floor is soft then the pump must be connected to a lifting apparatus with limited slack to
prevent the pump from burrowing into the soft floor.
3.2 Handling and Lifting
The HDS Submersible pumps are equipped with integral lifting lugs, designed to support weight
of the pump assembly for pump installation and removal. The weight of the pump is listed on
the pump data sheet in section 7.4 and also located on the pump nameplate. Ensure that the
lifting capacity of the rigging and lifting equipment is rated to lift the weight of the pump
assembly.
For lifting methods refer to:
Baldor® - Reliance® AC Submersible Motors
Installation & Operation Manual, MN414

3.3 Pipe Connections
Discharge piping and hose must be mounted and supported in such a manner that it does not
transmit stress to the pump casing. It is recommended that heavy duty, steel wire reinforced
elastomeric discharge hose be installed rather than traditional rigid discharge pipe. If rigid
discharge pipe is being installed then it is recommended that reinforced expansion joints be
incorporated into the discharge line.
The discharge flange details are as follows:

3.3.1 Optional Water Jacket Piping
If the pump is operating and the motor is drawing amps for more than 15 minutes below the
minimum water level, then a water jacket is required to cool the submersible motor, to prevent
the motor from overheating and possibly damaging the electric motor windings.
Cooling water Supply
Water Supply Clean mill duty water free from sand and grit.
Water Supply Flow Rate 5-10 USGPM (1.14 – 2.27 M3/hr)
Maximum Water Supply Temperature 104°F 40°C (40°C) Continuous Duty
Minimum Water Inlet Pressure ((Submergence Depth (ft) x S.G.)/2.31) + 5 PSIG
((Submergence Depth (m) x S.G.)/.102) + 34.5 KPA
Maximum Water Inlet Pressure ((Submergence Depth (ft) x S.G.)/2.31) + 10 PSIG
((Submergence Depth (m) x S.G.)/.102) + 69 KPA
Notes:
1. If one water supply line is utilized to supply both a water jacket and jet ring then it is
recommended to use a pressure reducing valve before the water jacket inlet fitting to
ensure the maximum water jacket working pressure is not exceeded.
2. Ensure that adequate cooling water is supplied to the water jacket while the pump is in
operation. Failure to supply adequate cooling water during operation can result in
overheating of the motor windings and possibly damage the electric motor.

standards. All electrical work must be performed by a licensed electrician. Always check the
motor data on the motor name plate to ensure that the electrical input parameters matches the
motor nameplate parameters.

4.0 Operation

4.1 Pump Start-Up Check List
Power and Control
Cables Check the power and control cables for damage such as cuts and tears in the out cable jacket.
Electrical Power Ensure the power supply parameters match the motor nameplate
data. Check fuses on each leg to prevent single phasing of the
motor.
Control Systems Check the moisture sensor relay and temperature sensor system to
ensure they are functioning and working correctly.
Electrical Connections Ensure all power and control cable connections are correctly
installed and the motor is properly grounded.
Rotation Check
(Bump Test) Ensure the pump is rotating CCW when viewed from the suction side of the pump. If the rotation is incorrect, switch two of the motor
legs in the control panel.
Pipe Connections Check all pipe connection bolt torques to ensure proper installation.
Ensure all pipes and hoses are properly supported and are not
pinched.
Cooling Water-Optional Check to see cooling water is flowing through the water jacket and
into the sump.
Flush Water-Optional Check to see the jet ring flush water is spraying out of the jet ring
nozzles.
Sump Check to see that all construction debris and foreign objects have
been removed from the sump.
Discharge Valve If possible ensure that the discharge valve is closed prior to start-up.
Once the pump is running open the discharge valve.

4.2 Pump Start-Up
It is recommended to commission your Vulcan Pump starting with a clean sump using clean mill
water as the medium. In cases where there is solids build up in the sump it is recommended to
dig out the solids prior to commissioning or re-installing the pump, this will allow the pump to
securely sit on the sump floor and eliminate construction debris and foreign objects from getting
into the pump during start-up. Once the pump is installed and commissioned, process solids
can be reintroduced into the sump.
If the sump cannot be cleaned out, the following procedures are recommended. Slowly lower
the pump into the solids / liquid mixture. It is imperative that the mixture of the slurry does not
exceed the applications maximum slurry concentration. If the maximum concentration is
exceeded, the flow rate of the pump is drastically reduced, which translates into a lower
discharge pipe velocity. The solids / liquid mixture requires a minimum discharge line velocity to
ensure the solids mixture stays in suspension and does not settle out plugging the discharge
pipe. It is recommended to monitor the output of the discharge line to ensure a consistent flow
rate of liquid and solids material.



UncontrolledCopy
17
Once the pump has found a stable operating condition, monitor the motor amperage draw. If
possible monitor the pump discharge pressure and flow rate. It is recommended that amperage
draw, discharge pressure and flow rate readings be recorded frequently to identify any changes
in the pump performance that could indicate possible problems with the pump or motor.
CAUTION!
CAUTION!
CAUTION!
4.3 Pump Shut Down

CAUTION!
Always flush the entire discharge line with clean liquid prior to shutting down the pump.
4.3.1 Pump Standby - Cold Temperature Applications
If the pump is removed from the sump when it is not being used, ensure the following:
1. Drain all of the liquid from the wet end components, water jacket, jet ring and piping.
Water expands when it freezes and can cause damage to equipment.
2. The oil in the motor seal cavity can thicken during standby and some of the elastomers
