57:1 Pump

Part 1601882-01

2012 Nordson Corporation

Description

The StediFlo 57:1 fluid pump is an air-operated, stainless steel pump

suitable for solvent-based and waterborne coatings. It is a double-acting

pump that delivers pressurized coatings on both the pressure and suction

strokes. Coatings are siphoned into the pump only on the suction stroke.

The pump can be used in both dead-end and circulating systems. In

dead-end systems, the pump stops when the pressure in the system equals

the pressure the pump can output given the input pressure. In circulating

systems, the pump strokes continuously to keep coating material moving

through the system at a rate set by the circulation valve.

Two sets of self-adjusting packings prevent coatings from leaking from the

pump during operation. The upper packings and plunger are lubricated by

solvent fluid in the solvent chamber. The lower packings are lubricated by

the coating material in the pump.

Filtered and lubricated compressed air operates the air motor and air value.

A safety relief valve in the air motor head prevents over-pressurization.
