Pipe connections
Male thread (1.5-inchMBT) with a 62 mm outside diameter.
We offer pump unions for 1.5-inch pipes.

Cable and plug
This pump is delivered pre-cabled without plug (length 280 cm). You can also choose to have the pump pre-cabled by our team with an AMP plug or a mini J&J plug.

An in.link plug is also available, but we recommend that you keep your existing cable if it's in good condition. Your pump may indeed be defective for many reasons, but the power cable is rarely to blame.

Similar pumps
The LX Whirlpool EA350 and DH1.0 pumps have the same motor power and thread size as the HA350, and roughly similar dimensions. If you want to replace your pump with another model, check beforehand the available space and the fixing distances as pipe connection adjustments may be necessary.
