Hand Pumps and Spindle Pumps

Hand pumps are offered in single-speed or two-speed versions for faster filling, delivering pressure up to 2.800 bar. They are suitable for many testing applications and also to be used as an industrial tool, allowing easy, quick and effortless bearing and shaft dismounting. High strength steel construction is more economical option but stainless steel construction is also available.

Hybrid liquid pumps (manual + air driven) are similar to air driven liquid pumps but they are equipped with hand lever to allow also manual acting. These pumps are mostly suitable for portable units, allowing automatic but also manual operation mode, or the combination of both. A perfect example is using pneumatic drive to fill and pressurize something and after achieving the set pressure, to rise pressure manually for a smoother control. These pumps offer maximum 860 bar or 2.200 bar.

Spindle pumps are suitable for generating with high precision high static pressures (up to 14.000 bar) in small volumes, without a stick-slip effect. Robust construction offers high lifetime.

Spindle pumps are also available with an electric motor drive, with additional stepper motor or synchronous motor added. For precise control, each pump is equipped with a position sensor to indicate the position of the piston. With this construction a higher stroke volume can be achieved than with manually operated pumps. Corresponding electrical control provided on request.
