Pressure Relief

SKIN INJECTION HAZARD

High-pressure fluid from dispense device, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

Follow Pressure Relief Procedure in this manual, when you stop dispensing and before cleaning, checking, or servicing equipment.

Relieve pressure in system by using two wrenches working in opposite directions on pump element and pump element fitting to only loosen fitting.

NOTE: When loosening pump element fitting, do NOT loosen pump element. Loosening pump element will change the output volume.

1.

Disconnect power source.

2.

Relieve pressure following Pressure Relief Procedure provided.

3.

Disconnect anything installed to pump element such as pressure relief valves, output union, or other fittings.

4.

Use a wrench to loosen pump element (1) and completely remove pump element and spacers (2) from

Adjusting Output Volume

NOTE:

• It may be necessary to repeat the outlet volume setup procedure after the pump is operating to re-adjust the volume of dispensed grease.

• The amount of dispensed volume can vary depending on external conditions such as lubricant temperature and back pressure from downstream connections. Use the volume adjustments provided in Table 1 as a starting point and adjust as necessary to ensure desired lubrication dispense.
