GU-30/30 pump

General information

Pumping capacity of 30,0m³/h, with a lifting height of 30mH2O and drive power required of 5,5kW.

The GU-30/30 pump is a new series of pumps, called the GU-30 series and are designed to meet the current requirements for food industry applications.
The pumps of this series are all made of acid-proof steel: the pump bodies and all parts are made of 1.4404 steel (316L), with an inner surface roughness of ≤0.8µm, and having washable components inside the body, including the seal.
Thickness of the materials used is min 5.0mm.

The GU-30/30 pump is designed for transporting non-condensed or condensed food liquids with a dry substance content up to 50%, or other food products of similar properties and a temperature up to 95°C.
The pump may be used in systems where food safety is crucial.

The pump may be used for:

  • transporting food liquids of viscosity up to 1000 cP,
  • dairy industry (milk, both fresh and pasteurized, whey, and liquid ice-cream mixes),
  • fruit-and-vegetable processing (thick juices, clarified juice, juices with fibre, fruit beverages, vegetable beverages, wines and fruit liqueurs),
  • distilling of alcohol (cereal mash and spirit products),
  • pharmacy,
  • pumping basic media in food industry (water, hot or cold purified water),
  • CIP system washing liquids,
  • other liquids

*after material set is agreed on

General characteristics

The GU-30/30 pump is a centrifugal pump that is, together with its motor, constructed as a closed, monolithic structure mounted on 4 ball-shaped legs, adjustable to make levelling of the pump possible.
The pump rotor is open and mounted on the extended motor shaft. The outer body is mounted with dome screws on the pump body. There is an O-ring placed between the outer body and the pump body, so that it is possible to wash it using the CIP system.
The outer body and the pump body are made of steel sheet 5.0 mm thick, specially shaped by forming to provide pump durability and reliability. The Rd Rd connector pipes with an external thread designed according to DIN 11851. Pump components coming into contact with the pumped medium are made of AISI 316 (1.4404) acid-proof steel while the other elements, like the casing or the base, are made of AISI 304 (PN-EN 1.4301).
Shaft sealing: double end-face mechanical - with the washing liquid (water), or single; the sealing material selected to suit the medium pumped.

Sealing sets available for the standard version:

Rubbing couples:
impregnated carbon/silicon carbide,
silicon carbide/silicon carbide,
impregnated carbon/ceramic.
Rubber materials:
Ethylene propylene EPDM
Fluoroelastomer (VITON)
Nitrile (NBR)

Other sealing materials available by request.

Advantages, certificates

The following advantages of the pump are worthy of notice: user-friendliness, low energy consumption, hygiene by design, easily washable components, and transportability (does not require a base).

The pumps are certified for use in the food industry, and have a declaration of conformity issued and CE certification.
