The MetaRock pressure/flow piston screw pump is designed for a convenient source of high pressure in the laboratory. It is designed for any application where a liquid is to be compressed or flow within a small volume to develop pressure. Utilizing sophisticated motion control and high resolution pressure transducers the pump can operate in a constant pressure or continuous flow modes. Refer to table for available volume/pressure ranges and flow rates.

Typical Applications:

  • Testing of instruments, gauges, component parts
  • Pressure measurement studies
  • Injection of liquid catalysts
  • Pressurizing chemicals

Refer to table for available volume/pressure ranges:

All wetted parts are of 316 stainless steel and 17-4PH stainless steel. Parker Poly Pak® is standard.

The automated pumps are designed where it can easily mount to a work bench and maximum pressures may be obtained with a minimum amount of effort by the operator. The standard connection is a High Pressure coned-and-threaded (HF4) opening for 1/4″ O.D. tubing up to 60,000 psi and XF4 connections for pressures above 60,000 psi. Adapters are available with optional Teflon packing at no additional cost for other type connections including pipe.
