This is a self-contained bench top set for studying the characteristics for various types of pumps.
The unit consists of four different types of pumps namely-centrifugal, turbine, reciprocating and axial flow pump, a common storage tank and measuring instruments. Each pump is driven by a motor dynamometer for measuring TRUE pump input power. Speed control is by an inverter. By manipulating flow control valves and a selector switch, each pump can be operated individually.
Instruction manual is also included.

| Learning Software |
| to support both online/offline training with data calculation and analysis by manual data entry from analog measuring instruments. | |
| Mercury manometer for axial flow pump, 300 mm x 1 mm graduation instead of differential pressure gauge |
| Note: Due to transport laws, mercury cannot be supplied. Buyer must source it locally. Approximately 25 mL or 350g is required. Filling kit is provided. | |
| Additional pressure gauges for individual pump |
| Additional centrifugal pump, pressure gauges and other accessories for series and parallel operation |
| Computer Interface (computer not included) |
| This includes HP405S and significant sensor(s) instead of analog measuring instrument(s), data acquisition (capture, display, graph and/or data export), additional software function for real-time data logging with computer interface unit and WiFi feature for data logging and real-time display remotely on smartphone (iOS and Android) |
- Other pump combinations can be arranged on request.
- Other optional equipment, please contact manufacturer ([email protected])
