CVHS-CVHM Pumps

Pump material

Stainless steel (AISI304/316)
Duplex stainless steel (2205)

Pipe connection

CVHS: DIN flange
CVMH: DIN flange | Clamp connection

Motor

Totally enclosed, fan-cooled, 2-pole standard motors
Enclosure class: IP55
Insulation class: F
Voltage: 3x380-415V

Liquid temperature °C

Normal temperature pump: -15°C to +70°C

Performance curves

All curves are based on the test value of the motor at a constant speed of 5200rpm, and the practical application can be adjusted to the selection of the head in the speed range of 4800-5350rpm.
Tolerances to ISO 9906
Measurements have been made with airless water at a temperature of 20 °C
The curves apply to the following kinematic viscosity: =1 mm²/s
Select a best efficiency of the pump which is operating within the bold curve of the pump performance.

Pump operating conditions

Pumping liquids which are thin, clean, non-flammable, non-combustible or non-explosive liquids, not containing solid particles or fibers.
Maximum ambient temperature: +40 °C
Maximum altitude above sea level: 1000 m

Ambient temperature

If the ambient temperature exceeds the 40 °C or the pump is installed at an altitude exceeding 1000 m, the motor output power P2 will decrease. In such cases, it is necessary to use a motor with a higher rated output.
