Electric motor driven hydraulically actuated dosing pumps with cast iron gearboxes

Low pressure industrial pumps,
Single or double hydraulic diaphragm,
Optional automatic control (stroke/speed),
Two international patents,
Diaphragm life: 20 000 hrs and more,
In accordance with API 675.



The MAXROY® range is very compact and robust, and is ideal for dosing at high flows and low pressures.

Features:
The absence of contour plates allows dosing of all types of liquids: clear, viscous, slurries.

Reliable, safe, robust:
An integral relief valve protects the pump from excessive pressure at discharge (The safety valve limits the pressure of hydraulic oil behind the diaphragm).
Complete sealing is provided by a single or double composite diaphragm with integral O ring.


Performance : Flows up to 1100 l/h,
Pressures up to 28 bar.


Principle of operation: The piston and the diapragm are connected by hydraulic oil to provide flow. Diaphragm life is long as it is not subjected to any load it just acts as a transfer barrier between the hydraulic oil and the liquid being pumped.
