Barnant Double Headed Hose Pump Type PDX/2

Barnant, Double Headed, Hose Pump, Type PDX/2




Barnant, Double Headed, Hose Pump, Type PDX/2The PDX and PDX/2 series is comprised of 6 different models. Their rugged cast housing, smooth tubing bed and high purity tubing are ideal for demanding pump applications in food, pharmaceutical, high purity chemicals and higher temperature applications.

The series offers the dry running design, which provides long tubing life, yet prevents system contamination should the hose ever rupture..

Flow capacities to 18 GPM single hose and up to 29 GPM in a unique dual hose design.


The hose design allows easy hose replacement without disassembly of the pump. The tube bed is designed with two flanges that prevent side to side movements of the hose.

Barnant, Double Headed, Hose Pump, Type PDX/2These 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
Variable frequency drives
Hazardous area rated drives
Wash-down
Chemical duty and Air operated 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.

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 <100 min-1 is suitable for continuous operation of the pump.
Speed range >100 min-1 is suitable for short-time operation of the pump.
