Mini Metering Pump

Roto's RJ Model Mini Metering Pump in modular construction, all stainless steel and options with various elastomers, has all the requirements for precise metering of various medias such as polymers, polyelectrolytes, hydrochloric acids, titanium dioxide, cellulose, gelatine, whey, yeast, sulphuric acid, ferric chlorides, ferric sulphates, hydrogen peroxide, etc.Constant non pulsating flow and high efficiencies makes this pump an ideal metering pump for various applications. No need for pulsation dampers! Flow is directly proportional to speed. Simple to operate.Applications such as clean liquids, liquids with solids, low to high viscosities, shear sensitive products, air or gas in liquids and chemically aggressive liquids are easily handled by the Roto RJ Pump.Installation can be arranged either vertically or horizontal configuration.Precise constant flows at high pressures with varying viscosities.Roto RJ Pumps are available in various drive configurations. With Direct IEC or NEMA C face motors, AC or DC Drives, Controllers, Gearbox and/or Gearmotors.
Advantages:

• Flow is directly proportional to speed: As you increase speed you increase flow, decrease speed decrease flow.
• No valves to clog, stick or vapor lock. Smooth non pulsating flow. Low shear rate for handling sensitive medias such as polymers, chemicals, dyes, food additives. Self Priming. Pressure capability independent of speed. True linear metering of product! Highly accurate and repeatability all the things that you require in a metering pump.
• Pumps are available with various sealing options.
• Stators are molded to size without the need of gaskets or o-rings, provides positive sealing. All elastomers are available in various materials from Buna, EPDM, Viton, HNBR etc dependant on media being pumped.
• The Roto RJ Pump are available in flows from as low as .003 to USGPM and pressures up to 350 psi.
