Rotary Lobe Pumps

Unibloc rotary lobe pump

Unibloc Rotary Lobe Pumps are quiet in operation, its optimal efficiency rotors push the products through from one end of the pump to the other. When the pressure gets too much, the oversized shafts help to prevent damage that other lesser pumps suffer.

Rotary Lobe pumps are used in:

  • Breweries (yeast)
  • Dairy industry (cream, yogurt, cottage cheese)
  • Confectionary (caramel, toffee, fondant cream)
  • Soft drinks industry for the likes of syrup and concentrates
  • Pharmaceutical industry on creams & ointments
  • Household & personal care for washing liquids, toothpaste, deodorants, shampoo & soap
Unibloc is available in a number of specialised variants –
  • Meat Pumps transfer raw meat and are fitted with special rotors allowing quick and easy replacement.
  • Road tanker Pump – lightest in class and available with either a bare-shaft or Hydraulic motor
  • Chocolate pumps – a heated rotor case and front cover, these pumps have tried and tested shaft seals for this difficult product
  • Fryer Pumps – designed to move hot oil from fryers, this version features hard faced seals with Kalrez O rings, special bearings and clearances

The Unibloc rotary lobe pump head is cited as the cleanest in the industry with its seamless design and porosity free guarantee as standard features.

Other features are as follows:
  • The rotors are supplied in non-galling alloy where pressure spikes might cause a lesser pump to seize, or in plastic. This is a cost-effective option for the meat processing industry where bits of bone cause frequent chaos
  • Oversized shafts which resist pressure are the backbone to the pump’s performance
  • The pump head interior and front cover have no pockets or crevices for products to become trapped, resulting in a fully CIP/SIP able design
  • Unibloc offer a wider range of shaft sealing options than ANY other lobe pump manufacturer
  • For the pharmaceutical industry,  pumps are available in a range of alloys, such as duplex or hastelloy and on much shorter delivery times than others
  • The gearbox is the toughest precision built in the industry in aircraft grade aluminium alloy or stainless steel
  • The Unibloc is available in a “Compac” design that bolts directly to a motor or gearbox flange reducing time spent in aligning different components on a baseplate
  • Safe design with no accessible moving parts
  • Our “Labtop” variants are a self contained laboratory pump that can be used in R&D facilities to test production techniques & processes. Full scale plant can use the larger Unibloc model without the need to re-validate processes.
