 Operating Principle:
Fluid Pressure generated by a screw pump acts on the bottom of a vertically free floating piston. The force produced pushes the loaded free piston vertically upwards. The piston floats freely in its cylinder and the pressure in the circuit will be determined by the weights loaded on the piston divided by the effective area of the piston with corrections for value of acceleration due to gravity, air buoyancy, surface tension and datum level difference.
Materials of Construction:
Piston: Tungsten Carbide/HCHC
Cylinder: Tungsten Carbide/HCHC
Internals: Austenitic 300 series Stainless steel
Mass Set: Austenitic 300 series Stainless steel
