Pump units

HI-FOG® pump units are a key part of system performance, as they must deliver consistently and reliably. The pump unit type and size is selected based on hazard type and areas to be covered.

Marioff offers five basic types of HI-FOG® pump units, each with variety of configurations:

  • HI-FOG® Sprinkler Pump Unit (SPU)
  • HI-FOG® Modular Sprinkler Pump Unit (MSPU)
  • HI-FOG® Machinery Local Application Pump Unit (MLPU)
  • HI-FOG® Sprinkler Pump Unit Diesel (SPUD)
  • HI-FOG® Gas Pump Unit (GPU)

HI-FOG® Sprinkler Pump Unit (SPU)

HI-FOG SPU Pump UnitThe HI-FOG® SPU is an electric pump unit suitable for many different applications. HI-FOG® SPUs can be custom built with a range of different sizes and configurations.  Each HI-FOG® SPU can be designed to connect to both main and emergency power supplies. HI-FOG® SPUs can provide continuous operation for extended protection using water tanks or an external water supply.

The pump units are self-supported and equipped with a break water tank and an electric control cabinet. An optional water separator is also available. For back-up, an additional electric motor can be provided.

HI-FOG® Modular Sprinkler Pump Unit (MSPU)

HI-FOG MSPU Pump UnitThe HI-FOG® MSPU is a modular version of the HI-FOG® SPU.  This type of pump unit is used when the installation space has limited access. The HI-FOG® MSPU can be carried through tight spaces in parts and then assembled at the final location.

 

HI-FOG® Machinery Local Application Pump Unit (MLPU)

The HI-FOG® MLPU is an electric pump unit mainly intended for machinery local protection applications. It consists of one electric motor driving a piston pump and a control cabinet.

HI-FOG® Sprinkler Pump Unit Diesel (SPUD)

HI-FOG SPUD Pump UnitThe HI-FOG® SPUD is a diesel-driven alternative to the HI-FOG® SPU. If electric power is not available, the HI-FOG® SPUD is provided as an alternative. The units are compact and self-contained, and can be customised as needed. They require no electrical connections, though they can be connected to external control and alarm systems.

HI-FOG® Gas Pump Unit (GPU)

HI-FOG GPU Pump UnitThe HI-FOG® GPU is a self-contained pump unit that does not need an external power source for operation. It is mainly used for low hazard areas and machinery spaces. In some applications, the gas is fed into the system with the water supply, which enhances the atomising of the water droplets.

The HI-FOG® GPU consists of a gas driven mechanical piston-type pump. It can use an external water system, a water tank or water cylinders. The gas can be either pressurised air or nitrogen depending on the application and preference. The unit size (number of cylinders) depends on the size of the protected space and the required protection time.
