Pump and Gear Meter Manual
(Click links for quick access)

This manual should be read entirely prior to the commencement of installation and operation. •
Only qualified personnel should install, operate and maintain this pump and associated equipment. •
Check pump for specific safety warnings/labels. •
Prior to start-up, ensure complete cleanliness and integrity of the system in which the pump is installed. •
In most cases the relief valve is factory set during performance test. In cases where the type of duty is not known •
(such as distributors or stock orders) or where the components containing the relief valve come from pre-tested
stock batches, it is not possible to factory set the relief valve. In this case it is the installer’s responsibility to set the
relief valve in accordance with the specific application.
Pumps with heat tracing or jacketing necessary to prevent solidification of the product should be brought up to •
working temperature prior to start-up.
All electrical work must be done in accordance with the manufacturers recommended procedures by qualified •
personnel.
Ensure all guards are securely in place before operating the equipment. Do not remove guards at any time during •
operation.
For pumps operating under ‘flooded’ suction, when venting the pump through a plug or valve, care should be •
taken not to completely remove vent plugs or completely open any vent as this could result in liquid being
discharged from the openings under pressure.
Prior to start-up, ensure that the system valves and associated equipment are correctly set. •
Wear appropriate safety atire including long sleeves, face shield, and gloves, whenever starting or operating the •
pump.

General Safety Precautions
1-1

Rotation and Flow
Start-Up Procedure
Pump should turn freely by hand. Ensure all 1.
guards are in place.
Heat if necessary. 2.
Gradually open valves, and check for signs of 3.
leakage before starting pump.
If possible, add some of the liquid directly to the 4.
pump. This helps lubricate and prime during the
first start-up.
Check the rotation by flicking starter 'ON' then 5.
'OFF'. (Correct rotation shown in diagram)
Start pump slowly - check for leaks - gradually 6.
increase speed.
Re-Torque Bolts
Thermal expansion can loosen bolt connections. It is advised that all
bolt connections get checked and re-tightened after initial heat-up,
and during routine maintenance.

If the pump is turning as
shown view above, the
Front valve is controlling
pressure. The rear valve
can not open in this
condition, as the fluid
pressure is pushing
against it.

Relief Valve Operation:
Each endplate can relieve pressure in one flow
direction only. As such, if the valves are set in
opposite directions, each can be adjusted to
independent pressures. It is possible to pressure
relieve at 80 PSI in one direction, while 30 PSI in
reverse.

Flow Speed Control:
Pump speed control, either in the form of a Variable
Frequency Drive (VFD) or hydraulic control valve is a
valuable feature. Many factors can contribute to a
situation where pump speed would need to be
decreased for cautionary reason, or increased for
efficiency gains. These controls have other built in
features such as motor protection and pressure control.
They also provide valuable information when trouble
shooting. Without control, one is left with limited options
when problems occur. This can lead to damage,
shortened life, or compromised safety.
Energy Savings from a VFD

Flow Speed Control
1-4
*Fixed Speed; Not everyone will choose some type of speed control. As a cautionary measure, we advise all fixed drive
systems start at a reduced speed. This should be as much as 50% below the pumps maximum. At initial start-up, this slower
speed is more forgiving When conditions are not as expected. Once the issues are corrected, the motor pulley can be
replaced with a larger pulley to increase speed as conditions allow.
The graph to the right shows the energy comparison of
Fixed Speed* with a VFD. Initially, fixed speed would
certainly be the least expensive. However, energy savings
should be considered during the cost analysis. At some
point this alone would cover the cost.

Liquid Lock Priming System
This is a specific combination of three
key elements that significantly
improve the pumps ability to prime;
Elevated Screen Inlet to Pump Inlet 1.
Pressure/Vacuum Boundary Plane 2.
Verticle Discharge 3.
This condition allows the pump to
prime at a very slow speed and in a
continual state of lubrication.
