MONO CMM 253 240V PROGRESSIVE CAVITY PUMP

CMM253

These pumps are not suitable for bio diesel
The key issues to be aware of are:
• Material incompatibility (many common rubbers, plastics and surface coatings will degrade from contact with fuels containing FAME)
• Fuel stability (may degrade over time by oxidation and hydrolysis)
These issues can affect storage tanks and pumps both on and off the machines using the fuel.
Whereas previously our M Range Pumps fitted with an RR stator used to operate comfortably with the standard 35secs Redwood Gas Oil (based purely on Hydrocarbons) and commonly sold as red diesel.
Since the changeover to modern fuel blends, the standard RR Stator can swell and fail as Diesel Biofuel (FAME) is overly aggressive towards rubbers and the only PC Pump Stator that can offer resistance is FKM (Fluorinated Rubber Material, NOV material code 'RV').
For this reason, and moving forward, NOV's warranty offered on a nitrile (NBR) build M Range will be invalid when pumping Diesel or Gas Oil Fuels with added biodiesel.


The Mono MM pumps are close coupled with a number of synchronous speed motors and are ideal for light industrial and domestic duties.

A single rotor and universal drive coupling enable the pump range to be small in size, whilst the robust construction ensures reliable service.

Flows of up to up to 1590 l/h and pressures up to 3.45 bar can be acheived.
