This pump is NOS (New Old Stock) and is delivered in 2008.
The original SRP was at that time +/- 1.200 euro.
A separate head for this pump is offered nowadays for around 650 euro and the electrical part for around 250 euro.

We offer this complete pump for 600 euro incl. VAT, excl. shipping.

The pump is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing.
The bearings are lubricatd by the pumped liquid.
In order to avoid problems in connection with disposal, great importance has been attached to using as few different materials as possible.

The pump is characterized by:

  • Three-speed motor.
  • Ceramic radial bearings.
  • Carbon axial bearing.
  • Stainless steel rotor can, bearing plate and rotor cladding.
  • Aluminium alloy stator housing.
  • Cast iron pump housing.
  • Stator with built-in thermal switch.

The motor is a 1-phase motor.
Twin-head pumps are supplied with a relay module in the terminal box.
The pumps may therefore be connected directly to the mains supply.
The relay module enables three different modes of operation.

  • Alternating operation.
  • Standby operation.
  • Single-pump operation.
