DAB PULSAR 50/80 M-NA 5" submersible pump for boreholes and wells – 1.3 kW, 1x230 V

Product detailed description

The DAB PULSAR 50/80 M-NA is a 5" multistage submersible pump with a stainless steel body, designed for boreholes and wells. This version has a single-phase 230 V motor with a rated output of 1.3 kW and is supplied without a float (NA). With the outlet closed it reaches a head of 75 m, about 50 m at 4.8 m³/h and 20 m at 7.2 m³/h.

What it is used for

• supplying a house with water from a well or borehole and boosting pressure
• pumping and transferring water
• garden irrigation and domestic gardening

Construction

The outer jacket, stator housing and filter cover are made of AISI 304 stainless steel, while the impellers, diffusers and suction filter are technopolymer. The hydraulic section sits below the motor; the motor, designed for continuous duty, is cooled by the pumped water. A double mechanical seal with an oil chamber in between (carbon/ceramic on the motor side, silicon carbide on the pump side) keeps the motor watertight and copes even with brief dry running. The rotor runs in robust ball bearings and the shaft is AISI 303 stainless steel.

Installation and electrical connection

The pump can be installed permanently or used as a portable unit, vertically or horizontally, down to an immersion depth of 20 m. It comes as standard with a 15 m H07RN-F cable. A maximum of 20 starts per hour is permitted. The single-phase version has built-in thermal and current protection and a permanently connected 30 µF capacitor. To connect a pressure or float switch, the CONTROL BOX PULSAR 1.75 for the 1.3 kW motor is available as an accessory. Have the connection made by an electrician.
