F1-27 – Centrifugal Pump Characteristics


F1-27 – Centrifugal Pump Characteristics

This accessory offers similar features to the F1-26, but with enhanced capabilities provided by the inclusion of a variable-speed pump with inverter drive rather than a fixed-speed pump.


This accessory comprises a variable-speed pump assembly and independent discharge manifold interconnected by flexible tubing with quick release connectors. This auxiliary pump is intended to be used in conjunction with the basic Hydraulics Bench.

The auxiliary pump is mounted on a support plinth, which stands adjacent to the Hydraulics Bench’s primary pump, with which it is intended to be used.

The pump speed is varied by an inverter drive. The motor speed, output voltage and motor current can be monitored on the inverter display. A compound pressure gauge is mounted on the pump inlet and a pressure gauge is mounted on the pump outlet.

An independent discharge manifold incorporates a pressure gauge and flow control valve prior to a discharge pipe with diffuser.
