Tesk TK In Line Pumps
Tesk TK pumps are single-stage vertical in-line centrifugal pumps with the suction and discharge on one line, for HVAC circulation, cooling, boiler feed and booster systems. Nine series cover DN32 to DN200 and up to 81 m head. Prices are for the bareshaft pump. This guide explains the model code, selection, dimensions and prices.

Reading the model code
TK65-34/2: DN65 suction and discharge, rated head 34 m, 2-pole motor (2900 rpm). A /4 model uses a 4-pole motor (1450 rpm) for larger flows.
Why an in-line pump?
The in-line design lets the pump drop straight into a horizontal pipe run with no bends, saving space in plant rooms. The pull-up design separates the motor from the pump body so the motor and seal can be serviced without disturbing the pipework.

Selecting a TK pump
- Flow and pipe size. Choose the series whose nozzle matches your pipe and flow.
- Head. For circulation, the head is the friction loss round the loop; for boosting, add static height and required pressure.
- Model. Pick the model whose rated point (shown on each product page with performance points) covers your duty.
- Motor. Prices are bareshaft — motor and build-up on request.

Frequently asked questions
Does the price include a motor?
No, TK prices are for the bareshaft pump. We quote motors and build-up separately.
What does /2 and /4 mean?
2-pole (2900 rpm) or 4-pole (1450 rpm) motor speed.
Can TK pumps handle hot water?
Standard pumps to +70 °C; the hot water type handles up to +105 °C.
Need a circulation or in-line pump sized?
Send us the flow, the head or loop pressure drop, the liquid temperature and the pipe size.
