CVFH Pumps

CVFH Super High Pressure Pumps

CVFH are high-efficiency and energy-saving vertical multi-stage centrifugal pump. The centrifugal force generated by the impeller of the rotary pump drives the fluid to transfer. Its pump body and motor are composed of main shaft, impeller, diffuser, pump case and mechanical seal, and connected by coupling.

CVFH series can be used as booster pump alone or as auxiliary booster equipment in the booster system of construction and industry. Its piping structure ensures that the pump is directly installed in the same horizontal piping system with the same diameter in and out.
This design makes the structure and piping of the pump more compact.

CVFH series vertical multi-stage centrifugal pump can be installed vertically or horizontally on pipeline according to different installation space. In the case of horizontal installation, the pump needs to be added with fixed module to ensure the stability of the pump during operation.

Liquid temperature °C

Normal temperature pump: -15°C to +70°C
Hot temperature pump: -15°C to +120°C

Performance curves

The motors used for the measurements are based on 2900rpm or 2950 rpm
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.
