Moyno launched a range of dosing pumps for applications where low flow, accurate dosing is required. The new dosing pumps provide a smooth pumping action with no pulsation and very low shear. The pumps are suited for intermittent or continuous dosing duties in high pressure, low flow applications and represent an alternative to more expensive gear pumps traditionally used for these types of duties, according to the company.
The dosing pumps offer the option to transfer low flows at high pressure (1,044 psi/72 bar). With no valve components (reducing the number of wearing parts), blockages are eliminated and the working pump life is extended. Stators are available in a variety of different materials, enabling the pumps to handle a wide variety of applications and resist wear. Maintenance can be completed without the need for any specialist skills.
Manufactured to ISO 9001:2008 quality assurance standards, the modular design of the new dosing pumps allows the four models in the range to cover performance requirements from 0.53 US GPH (2 liters per hour) and 1,044 psi (72 bar pressure), up to 330 US GPH (1,250 liters per hour) and 174 psi (12 bar pressure). All the pump components, with the exception of the body, coupling rod and suction chamber are supplied in stainless steel as standard. Internal pump components can 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 frequency inverter.
