Description

A line of pumps offering an efficient, reliable and low maintenance solution for applications where low flow, accurate dosing/metering is required. The dosing/metering pumps provide a smooth pumping action with no pulsation and very low shear. Ideal for either intermittent or continuous duties.

Description
The pump is ideal for either intermittent or continuous dosing duties in high pressure, low flow applications, and represents a cost-effective and reliable alternative to the more expensive gear pumps traditionally used for these types of duties. Manufactured to ISO 9001:2008 quality assurance standards, the modular design of the new dosing pump allows the four models in the range to cover performance requirements from 5 liters per hour up to 1,250 liters per hour and 72 bar pressure.
