Immersible Pump — Model Range

Choosing a TPRK_E, TPHK or TPK Immersible Pump

Immersible pumps are vertical multistage centrifugal pumps that mount on top of a tank with the pump end immersed in the liquid and the motor above it. They are designed for industrial use, particularly machine tools, moving water, coolant, light oil and other clean, non-aggressive fluids. The main working parts are stainless steel, the pumps are self-priming, and the motors are IP54 with Class F insulation. Liquid temperature is rated from 0°C to +90°C, with a minimum submerged depth of 40 mm and flows of up to 650 L/min.

Three series are listed. The TPRK_E series uses a coupling connection with a cartridge-style mechanical seal and a drain-back tank, so liquid returns to the tank even if the seal leaks; it is offered in sub-series from 1T to 20T. The TPHK series mounts the impellers directly on an extended motor shaft for a compact co-axial design and uses IE3 efficiency motors. The TPK series completes the range. Motor outputs across the page run from 0.22 kW to 18.5 kW, with 50Hz and 60Hz versions.

In a multistage pump each extra impeller adds head, so the model code indicates the number of impellers and the standard capacity. Choose the capacity for the flow your coolant system needs, then the number of stages for the required pressure.
