The Pk series is comprised of 4 different models. The sliding shoe technology combined with a lubricated bath provides a simple, reliable pump mechanism with proven long hose life in continuous operation.

The sliding shoes are adjustable which allows the pumps to be set up for specific application needs. by adjusting the shoes you can set the maximum pressure produced by the pump and increase the hose life.

With flow capacities to 68 GPM these pumps can easily develop a discharge pressure up to 220 PSIG (15BAR).

The hose design allows easy hose replacement without disassembly of the pump. The hose connectors are uniquely designed to eliminate multiple parts, yet provide a positive seal capable of holding the maximum pressure ratings.

These pumps are shipped as complete pump, motor, drive systems ready to install and start up. Standard motor drives are fixed speed.

Optional drives include:
• Mechanical Variable Speed
• Inverter Variable Drives

The standard inlet and outlet connections provided are barbed hose type. Optional inlet and outlet connections available include ANSI 150# flanges, Sanitary Tri-Clamp fittings, and NPT connections.

Characteristic Lines

	The pump characteristics give approximate values for the conveying capacities at various pressures. They are related to the pumping of water. For materials with higher viscosities lower capacities are to be expected. Speed range <50 min-1 is suitable for continuous operation of the pump. Speed range >50 min-1 is suitable for short-time operation of the pump.
