Peristaltic metering pump

Peristaltic pumps for metering (LPP-M) from Flowrox are designed for pumping diverse slurries and accurately metering a wide range of media while upholding chemical resistance. Made from thermoplastic materials, the pumps use tube technology to ensure secure operating conditions for the environment and operators. The pumps provide superior accuracy because the flow rate is not affected by variation of the discharge pressure. Positive displacement of the tube bore with zero slip provides the same output volume on every cycle. 410/636-2250; www.flowrox.com.

 

Peristaltic hose pumps

Abaque Series peristaltic hose pumps from Blackmer handle abrasive, aggressive, shear-sensitive and viscous materials. The pumps are constructed with ductile iron and steel, allowing discharge pressures to 217.5 psi. The seal-free design eliminates leaks, contamination and product loss while reducing maintenance and repairs. Hoses are available in natural rubber (resistant to diluted acids and alcohols), Buna or NBR (wear resistant to oily products), and EPDM (high chemical resistance with concentrated acids, alcohols and ketones).

The pumps are available in nine sizes and in flow rates of 0.7 to 211 gpm and are self-priming to 29.5 feet manometric lift. They can run dry continuously, handle high solids concentrations, and run in forward or reverse. 616/241-1611; www.blackmer.com.

 

Submersible mixers

Amamix and Amaprop horizontal submersible mixers from KSB mix, homogenize and suspend sludge.
