Grundfos Hygienic self-Priming (GHP)

Posted by on Saturday, 28 March, 2015

Grundfos’ new range of GHP (Grundfos Hygienic self-Priming) pumps takes efficiency and durability to new levels in sanitary processes.

The pumps are based on the well-known HILGE technology and are further optimised to offer reliable operation even under the tough conditions encountered in cleaning processes.

The single-stage self-priming GHP pumps combine the best of the F&B-HYGIA end-suction pumps with the reliable HILGE technology. The result is an optimised pump range that comes with increased efficiency compared to traditional side-channel pumps and can be counted on for long operational life.

 

One pump – More applications

Due to the robust construction of the new GHP pumps they are able to handle liquids with a high content of air as is the case in CIP return systems.

In effect, this means that the same pump can be used for product conveyance as well as for the cleaning processes. Compared to side-channel pumps, GHP pumps are also less sensitive to handling products containing particles.

Low noise operation

The GHP pumps feature a new, unique hydraulic technology that allows the impeller to be adjusted to accommodate exact duty-point requirements.

This translates into a noise level significantly lower than compared to traditional side-channel pumps.

Specially designed for sanitary applications

The all-stainless steel GHP pumps have been specially designed for trouble-free operation in sanitary processes such as:

  •  Cleaning processes (CIP return)
  •   Evacuation of tanks and pipes
  •   Pumping liquids with a high gas content
  •   Pumping liquids in Food and Beverage industries

Grundfos Backwash

Posted by on Wednesday, 25 March, 2015

 

Backwashing refers to the reverse-pumping of water, for example for the periodic washing of filters. Grundfos can supply pumping solutions that deliver the very strong force with well-executed flush times and speeds required for effective backwashing.

Backwashing is a form of preventive maintenance to prevent further clogging of the filter medium. Backwashing in water treatment plants is an automated process, usually run by programmable logic controllers (PLCs). The backwash cycle is usually triggered when the differential pressure over the filter exceeds a set value.

 

Grundfos can supply pumping solutions to cope with the hugely varying flow requirements for backwashing, ranging from huge split-case and mixed-flow pumps, where the focus is on moving water rather than added pressure, to our highly successful vertical multistage centrifugal pump (CR) – and covering all performance requirements in between.

Grundfos can supply the specialist expertise to help meet your performance objectives, from the initial identification of needs, to the selection, installation, operation, and maintenance of the pumping solution. Grundfos commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.
