Application
MVL pumps are used for pumping clean or almost clean liquids with viscosity similar to that of water.
The MVL pumps can be used in:
water supply systems
water works systems
water treatment systems
air conditioning systems
industrial water circuits
fireproof systems
Constructional execuion
The MVL family comprises single-staged centrifugal normal intake pumps characterised by tight construction with a closed rotor; both short pipes (pumping and intake) share the same symmetric axis ('inline' pump). The intake and pumping short pipes are compliant with the ISO 7005-2/PN 16 standard.
The dimensions of the flanges of the intake and pumping short pipes are compliant with the ISO 7005-2/PN 16 standard.
A special modular system used in the pump enables one to uninstall the whole bearing set (including rotor and container) without the necessity to dismount the installation.
All rotors are statically and dynamically balanced in compliance with the ISO 1940 standard, class 6.3.
MVL pumps are connected to the motor using a rigid coupling (for W1 and W2 – sleeve coupling, for W3 – faceplate coupling).
The pumps are driven by asynchronic air-cooled electric motors compliant with the VDI and IEC standards.
This type of pump is equipped with a single mechanical seal. The material options for the pump are dependent on the pumped medium.
Currently, the pump is produced in one basic option as specified by the following product specifications: e e1 e1 e4 = 1010. The pump features a single, non-balanced mechanical seal.
