DESCRIPTION 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 F1-10/F1-10-2. 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. The auxiliary pump is mounted on a support plinth designed to be positioned on the floor besides the hydraulics bench , adjustable feet allowing levelling. TECHNICAL SPECIFICATIONS Pump: Centrifugal type Max head : 21m H2O Max flow: 1.35 L/s Motor rating: 0.36kW Speed controller: Frequency inverter Speed range: 0-1500 rpm Pressure gauge range: 0-60m H2O Compound gauge range: –10 to +32m H2O See Hydraulics Bench F1-10 technical details for primary pump characteristics EXPERIMENTAL CONTENT Determining the relationship between head, discharge, speed, power and efficiency for a centrifugal pump at various speeds Determining the head/flow rate characteristics of two similar pumps operating in either parallel or series configuration at the same speed
