The DAB PULSAR is a multistage, close-coupled borehole pump with the hydraulic part below the motor.

Submersible electric motor cooled by the flow of pumped liquid and sealed with a double mechanical seal and oil chamber.

Applications

PULSAR electric pumps are utilised for:

  • Lifting clear water from boreholes, first water collection tanks or cisterns
  • Wells or water courses
  • Distributing pressurised water to domestic installations, small agricultural plants, and sprinkler systems for lawns and vegetable gardens.

The pump has a very silent operation, and can be installed inside boreholes and tanks, thus avoiding all the potential problems connected with suction and unpriming.

  • Constructed in compliance with CEI 2-3 and CEI 61-69 (EN 60335-2-41) standards.
  • Operating range: from 0.9 to 7.2 m3 /h with head up to 86 metres.
  • Maximum permissible sand quantity: 50 g/m3.
  • Motor protection level: IP 68.
  • Insulation class: F.
  • Liquid temperature range: From 0° C to +40° C.
  • Standard cables: 20 m HO7 RN F cable type.
  • Cable complete with SCHUKO plug EEC 7-VII-UNEL 47166-68 for the single-phase version.
  • Impellers, diffusers, strainer and oil sump in abrasion-proof thermoplastic material.
  • Outer liner, stator sleeve, upper head with delivery connection and closing ring in AISI 304 stainless steel.
  • Upper and lower bearing support in pressed anti-dezincification brass.
  • Rotor shaft extension in AISI 304 stainless steel.
  • Elastomers in NBR.
  • Stainless steel screws.
  • Double mechanical seal with interposed oil chamber, in ceramic/carbon on the motor side, and silicon carbide/silicon carbide on the pump side.
  • The seal system adopted ensures watertight sealing of the motor and good performance of the mechanical seal even in the event of short term dry operation.
