| Low piston clearance and optimized design of inlet and outlet valves | Very high and constant volumetric efficiency on a wide speed (100 up to 5000 rpm) and pressure range |
| Permanent self lubrication and cooling through suction flow | Improved lifetime and low noise |
| Sturdy construction of bearings and optimal design of the suction valves | Improved reliability even in rough ambient conditions (high temperature, severe vibrations) and restricted space conditions |
| Automatic venting by raising and lowering the pressure or by switching the motor on and off several times | Enables supply of standard pumps as well as special customized models |
