Metering Pumps feature single-piece rotating unit.

Press Release Summary:




Available in 4 sizes with capacities to 2.5 gpm, pressures to 174 psi, and speeds from 0-600 rpm, MDP Series features 1-piece rotating unit made from Xytel ST801 nylon, which is virtually unbreakable and resistant to abrasion. Progressive cavity pumps provide pulse-free metering of low- to medium-viscosity fluids with accuracy up to ±1.0%. They can be equipped with electric motor with integrated frequency inverter and forced ventilation, or with mechanical variable speed drives.

Low-Cost Metering Pump Re-Engineered for Added Durability



The seepex MDP series progressive cavity metering pumps now feature a rotating unit made from Xytel ST801, a "super tough" nylon. The material is virtually unbreakable, is more resistant to abrasion than stainless steel, and runs reliably at low speeds and under high pressure.

Conventional progressive cavity pumps have a rotating unit consisting of ten individual parts. The patented MDP rotating unit is injection molded as a single piece, which is significantly less expensive than conventional units, easier to maintain, and much faster to replace.

The new MDP provides pulse-free metering of low- to medium-viscosity fluids with repeatable accuracy up to ±1.0 percent. The pumps are available in four sizes with capacities from 0.1 to 580 l/h (2.5 gpm) and pressures to 12 bar (174 psi). They can be equipped with a specially designed electric motor with integrated frequency inverter and forced ventilation, or with mechanical variable speed drives. Speed can be controlled from 0 to 600 rpm by either a manual potentiometer or an external analog signal.

These units are best suited for industrial wastewater, flocculants and other water-based chemical solutions, emulsions or slurries. They are not recommended for use with aggressive chemicals such as concentrated chlorides, ketones and most hydrocarbons.
