The PA series of triple screw pump is specifically designed for applications where there are space limitations. This range can be submerged in the oil and is excellent for lubrication and cooling applications. It can handle various hydraulic and lubricating oils ranging in viscosities from 10 to 400cp. The PA range can produce flow rates up to 51m³/hr and high pressures up to 50 bar.
This submersible screw pump can be fitted with either standard BSP connections or can come supplied with a filter on the suction port to protect the pump.
Our screw pumps have numerous benefits over other positive displacement pumps such as gear pumps. They produce low noise levels, are compact as no gearbox is required, produce low pulsations, are excellent at self-priming and can handle fluids containing trapped air.
The PA series can be fitted with an Atex motor for installation in non-safe areas. It is marine type approved by ABS, BV and RINA and can be marine witness tested by various classification bodies if required.
The PA series of triple screw pump can be manufactured in various grades of cast iron and can be utilised for various applications within the marine and industrial markets.
