Koller - 0.54 HP Circulation Pump with Centre Suction - PPS-10388

Koller – 0.54 HP Circulation Pump with Centre Suction

The Koller 136-400 WC is a 0.54 HP (400 W) hot tub circulation pump with centre suction, designed for 24-hour operation and found in many European spas. It comes pre-cabled with an AMP plug, so it is a straightforward replacement for a worn spa circulation pump of the same type.

Compatibility and use of the Koller 136-400 WC

This Koller 0.54 HP circulation pump is found in many European spas. Before ordering, compare the part number on your existing pump with 136-400 WC, and check that the power rating, the centre suction layout and the plug type match your hot tub.

The drain hole at the bottom of the faceplate is closed with a plug. If you need to replace it, the plug for the Koller circulation pump is available as a spare part.

Technical specifications and dimensions

• Power: 400 W (0.54 HP)
• Speed: 2800 rpm
• Maximum flow rate: 315 litres/minute
• Length: 280 mm
• Width: 136 mm
• Height: 180 mm

Compare these dimensions with the space in your equipment bay to make sure the replacement pump will fit.

Connections and plug types

The pump has a thread diameter of 62 mm (1.5-inch MBT). The pump unions are not included, but are available separately. A 62 mm pump union for 1.5″ pipe suits this connection.

The pump is delivered pre-cabled with an AMP plug on a 3 m cable. Koller circulation pumps are used with these plug types:

• AMP plug
• J&J plug
• in.link plug

If your installation uses a mini J&J plug, you need an adapter from AMP to mini J&J (sold separately). Alternatively, you can reuse the cable from your existing pump if it is in good condition.

Other Koller circulation pumps in the same series

Other Koller circulation pumps with centre suction from the same series are also available: the 0.16 HP, the 0.27 HP and the Koller 0.40 HP circulation pump with centre suction. Self-drain versions are offered as the 0.27 HP and the 0.54 HP.

The self-drain models are not the same as this centre suction pump, so check which type is fitted to your spa before you order.
