The rotary-lobe pumps of the series SKK are particularly for gentle transport of products with a viscosity ranging from liquid to high-viscous and pasty.

Key data
  • Pump capacity 60 - 3,400 cm³ / rev.
  • Allowed pressure depending on the application up to max. 20 bar
  • Viscosity range depending on the application up to 100,000 mm²/s
Features

The series of the types SKK offers a wide range of different variations and constructions for the transport of nearly all pumpable media.
The pump consists of the gear component with synchronous drive of the two rotary pistons and the part of the pump containing the casing with suction and pressure joint and the two rotary pistons.

The sturdy bearing is located in the gear component, protected against the pumping liquid by different seals. On the other hand, special seals prevent any leaking of the transmission lubricant out of the gear component.
Since the pistons and the walls in the pump rooms must not touch each other in a rotary piston pump, a slight slipping cannot be avoided. However, it only shows when products of low viscosity (e.g. water) are pumped against pressure. In this case the lower speed range cannot be used.

Products having a viscosity of more that approx. 300 mm²/s (cSt) hardly show any slipping. The volumetric efficiency for these products is nearly 100%.
The suction capacity of the SKK pump very much depends on the viscosity and the speed. The maximum suction head is approximately 4 m.

It is easy to clean and to maintain. All parts of the pump have easy access for inspection and cleaning once the nuts have been unscrewed and the cover has been taken off. The pipe connections do not have to be removed.
If products are pumped that do not stick or become hardened, it is sufficient to rinse the rotary piston pump well with water or any suitable solvent. Thus the pumps cleans itself.

If the pump is used in the food industry, in the pharmaceutical and the cosmetics‘ industries, the rotary piston pump SKK has a special construction so that it can be dismounted quickly. Thus all parts coming into contact with the product (casing, pump, etc.), as well as the sealing parts can be easily reached for cleaning. There are no dead corners, uncontrollable pits etc. The pump can also be sterilized by blowing steam through it..
