Technical data

Operating conditions

During continuous operation, the suction strainer must

always be completely covered by the liquid.

Installation

Unilift KP-S requires a minimum of space. If the pump is

installed in a pit, the pit diameter must be minimum

200 mm to avoid too many starts and stops.

Use the recommended dimensions in the table below.

Fig. 9

Pit dimensions, Unilift KP-S

If Unilift KP-A is installed in a pit, the minimum pit dimen-

sions must be as shown in the figure below.

Pump positioning

Unilift KP-M and Unilift KP-A can be used in the vertical

position with the discharge port uppermost or in the

horizontal or tilted position with the discharge port as the

highest point of the pump.

Unilift KP-S must be used in the vertical position.

Fig. 11 Pump positions

Level switches

A level switch starts and stops the pump between two

liquid levels. This type of installation requires a non-return

valve in the discharge pipe or the pump. Unilift KP pumps

are available with two different level switch types.

Unilift KP-S with electronic sensor

The sensor is integrated in the pump. Consequently, the

difference in level between start and stop cannot be

adjusted.

Unilift KP-A with float switch

A clamp on the pump handle holds the float switch cable.

The difference in level between start and stop can be

adjusted by changing the free cable length between pump

handle and float switch.
