A new range of dosing pumps launched by NOV Mono has been designed for applications where low flow, accurate dosing is required. The new Mono dosing pump aims to provide a smooth pumping action with no pulsation and very low shear. The pump is suitable for either intermittent or continuous dosing duties in high pressure, low flow applications. The new dosing pump offers the option to transfer low flows at high pressure (up to 72 bar/1044 psi). With no valve components blockages are eliminated and the working pump life is extended. Stators are available in a variety of different materials and enable the pump to handle a wide variety of applications, and again, increase the pump’s resistance to wear.
Four models
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 25 litres per hour (0.11 USGPM) and 72 bar pressure (1044 psi), up to 1,250 litres per hour (5.5 USGPM) and 12 bar pressure (174 psi).
All the pump components, with the exception of the body, coupling rod and suction chamber are supplied in stainless steel as standard, and have the option for internal pump components to be supplied in Hastelloy, which allows the pumps to be used in severe chemical environments. Other optional features include a range of fixed or variable speed drives with mechanical variable speed or a frequency inverter.
