Maintenance Schedule

Flushing and Storage

Establish a preventive maintenance schedule based on the pump’s service history. Scheduled maintenance is especially important to prevent spills or leakage due to diaphragm failure.

Lubrication

The pump is lubricated at the factory. It is designed to require no further lubrication for the life of the packings. There is no need to add an inline lubricator under normal operating conditions.

Tighten Threaded Connections

Before each use, check all hoses for wear or damage and replace as necessary. Check to be sure all threaded connections are tight and leak-free. Check mounting bolts. Check fasteners. Tighten or retorque as necessary. Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque Instructions, page 16.

Flush before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment.

Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary.

Use solvent that is compatible with the equipment wetted parts and the material being dispensed.

Always flush the pump and relieve the pressure before storing it for any length of time.

NOTICE

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it.
