IFB #26-02 Two Pump Laboratory Trainers

The Massachusetts Maritime Academy is seeking bids for the purchase of two Pump Laboratory Trainers for students and instructors to utilize at the Academy's laboratory space. The trainers must have specific capabilities, including measuring head, flow, power, and efficiency characteristics of a centrifugal pump, and must have a throttling valve on the discharge side of the pump. The bidder must provide relevant information about their company's knowledge and experience with providing equipment related to the Pump Laboratory Trainer. The successful vendor must provide an account representative who will be available to assist the Academy in the commissioning and troubleshooting of the trainers. • The Pump Laboratory Trainers must have the ability to measure the head, flow, power, and efficiency characteristics of a centrifugal pump at constant motor speed over a range of discharge back pressures and flow rates from zero (shutoff) to maximum pump capacity. • The trainers must have a throttling valve on the discharge side of the pump to vary the back pressure. • The trainers must have the ability to maintain a constant motor speed across different discharge pressures with either manual or computer control. • The trainers must have at least three (3) centrifugal impellers with forward swept, rearward swept, and straight vanes to permit the variation of the pump specific speed. • The trainers must have the ability to lower the absolute suction side pressure to below the vapor pressure of the working fluid at room temperature to cause cavitation to permit measurement of the required net positive suction head (NPSH) characteristics of the pump over a range of flow rates.
