BMF hollow disk volumetric pumps

Technical features

Operating principle

The oscillating hollow disk moves inside the pump body creating two different volumes, the suction volume and the discharge volume. The two volumes are separated by a diaphragm and the fluid passes through the openings of the pump body.

The hollow disk is pressed against the body walls by a spring allowing the working principle to be elastic and the solid bodies’ transit is allowed too.

•MAX WORKING PRESSURE:
7 BAR IN STANDARD VERSION
20 BAR IN HIGH PRESSURE VERSION

Features

SELF PRIMING
Vacuum creation in suction side
REVERSIBLE
Same features in the two senses of rotation
ELASTIC
The hollow disk system works well with every fluid viscosity and enables the passing through of little suspending solid parts
LOW ROTATION SPEED
Low rotaion speed means high reliability and fluids are never emulsified
