■ Food industry: Cooling and deep-freezing with natural and
synthetic refrigerants
■ Sports and leisure facilities, such as: Bobsled tracks, ice rinks
or ice hockey stadiums
■ Electronics and power converters: modules in mobile (railway)
and stationary (offshore wind turbines) applications
■ Cooling modules in the chemical industry (optionally in
explosion-proof design)
■ Freeze-drying and oil-cooling systems for transformers
■ CO2
cooling for mainframes and server centres
■ Absorption refrigeration applications with lithium bromide and NH3


Pumped media

Liquids and liquefied gases, such as NH3
(R717), CO2
(R744), R22, R134a,
hydrocarbons, R404a, R11, R12, Baysilone (M3, M5), methanol, silicone oil
KT3, Syltherm XLT, water glycol mixtures. In principle, the refrigerant pumps
are suitable for conveying all types of refrigerant. However, this must be
checked for each case.

Type /design

Horizontal, seal-less section-type pumps with completely closed canned
motor, with radial impellers, multi-stage, single-flow.


Canned motor pump type CAM

This pump is suitable for conveying liquids near vapour pressure and for
standard applications.

Canned motor pump type CAMR

The CAMR pump with radial suction port is particularly suitable for compact
systems with small collecting tanks. Due to the degassing on the suction
side, the pump is ready for operation sooner after switching off. The pump
can be suspended directly under the tank to save space.


The rotor lining – one of our core competencies – is manufactured by impact
extrusion and, as a nickel-based alloy, is an essential component of the
highly efficient canned motor. The liquid-filled canned motor accelerates
to operating speed within seconds and operates wear-free and maintenance-free
in continuous operation due to the hydrodynamic plain bearings. The
canned motor is low-noise and low-vibration and offers double security
against leakage.
