For use in oil circulation lubrication systems

ZM multi-circuit gear pump units are self-priming and valvelesspumps. They are used in oil circulation lubrication systems with 5to 20 separate delivery circuits. Unused outlets must be returnedto the reservoir. The pumps consists of an electric motor, adapterflange, coupling and a gear pump. The pump can be mountedseparately from the reservoir or as a flanged pump on thereservoir. A special design with seals for horizontal mountingbelow lubricant level is available. The fluids to be pumped musthave enough lubricity for the pump to lubricate itself.

Some of these distribution pumps require an attached,single-circuit priming pump that operates separately. The primingpump restricts differential pressure within the multi-circuit pumpsand helps to provide uniform delivery rates. It is advisable tofilter the oil upstream of the distribution pump inlet.
