Technical Information

Hammelmann pumps in detail

Compact construction

Hammelmann pumps produce maximum performance from a minimal footprint which is the result of combining a compact integral speed reduction gear end with the concept of a vertical configuration.

Compact construction
 
 

The vertical configuration directs oscillating forces directly downwards into the base structure. Unwanted lateral oscillations as produced by horizontal pumps do not occur.

 
 
Twin helical gears
 
 

The integral speed reducer with twin helical gears arranged in a herring bone configuration ensures smooth running and even power transmission without axially loading the bearings.

Gear ratios
 
 

A selection of gear ratios is available to allow the optimal choice of driver. The compact construction eliminates the need for an external gear box and prevents rotary oscillation. Mechanical efficiency is in excess of 95%.
