Gianneschi PQ40 (230/400V) self-priming gear pump

The Gianneschi PQ40 gear pump is a professional, self-priming, high-flow solution. It is designed for the rapid and safe transfer of large volumes of low- to medium-viscosity liquids. It offers the versatility of being compatible with 230V and 400V three-phase AC systems, making it ideal for industrial environments and large vessels.

Modular Design (PQ Series) and Robustness

The PQ series features a modular architecture: the pump is coupled to the motor via a bell housing and flexible coupling, using a standard IEC-compliant motor. This design facilitates maintenance and ensures industrial-grade robustness, guaranteeing a long service life. The gear mechanism ensures a high, constant flow rate and strong suction capacity, even with slightly viscous fluids.

Safety and Applications for Hydrocarbons

The pump is ideally suited for transferring clean fluids (without suspended matter), including:

• Diesel (Gasoil)
• Biodiesel
• Oil (Engine or Hydraulic)

It incorporates a bypass valve, an essential safety feature that protects the engine and piping system from overpressure or blockages.
