Specified for sampling and processing applications requiring 100% sanitation assurance, the MityFlex line of contamination-proof peristaltic pumps are designed for increased flow accuracies and efficient operation. Features include multiple roller heads to reduce pulsation and quick-release covers for fast change-out of tubing. The pumps are seal-less and self-priming with consistent positive displacement, capable of handling a wide variety of viscosities from air or gases to heavy slurries. Variable speed controls have flow rates ranging from 0.4 to 3,800 ml/min. Voltages range from 24 to 240 ADC VAC in 60 or 50 Hz and 12 to 24 VDC. Prototypes and custom orders are welcome and samples are available.

Pump brochure. Covering industrial-duty Internal Gear pumps, Rotary Lobe pumps and high-pressure and composite-material External Gear pumps, this brochure includes numerous cutaway images to illustrate each of the pumping prin-ciples. Gerotor pumps for OEM applications, gear reducers, basket strainers and Flow Manager meterless flow and pro-portioning controllers are also described.

Medium-speed pump. The MSP variable-speed, vertical inline pump follows API 610 8th edition design criteria. Op-erating benefits include hydraulics designed for low-flow high-head applications and a medium speed induction motor with variable frequency drive for optimal BEP and adaptability to a range of changing service conditions. No gear box or lubrication system is required and all auxiliaries are included.

Diaphragm metering pumps.
Designed for pressures from 70 to 280 psi and flow rates from 0.65 to 360 gph, the ecodos series of mechanically actuated diaphragm metering pumps features a patented 3-layer PTFE sandwich dia-phragm that provides back-up double-containment safety. Complete descriptions, specifications, dimensions, line draw-ings and optional equipment and accessories are included with the free brochure.

Pneumatic piston pumps. Designed to provide clean efficient and economical pumping of viscous pastes, resins, grease, paints and creams from open-top drums, these air-powered piston pumps can handle up to 1 million centipose without requiring the material to be heated. With no electric motors or starters, the pumps are explosion-proof. The
motor is designed to operate quietly and reliably, and it can be stalled without damage.
Granzow Inc, Charlotte, NC. www.rsleads.com/204df-242
Seal-less pump.
Matched with 24 VDC brushless motors, the RD seal-less pump line offers life-expectancy in excess of 25,000 hours. The canned motor design makes a compact envelope and nose-up mounting into a reservoir possible. Integral controllers ease wiring and regulatory compliance. Applications include fuel cell coolant recirculation,
electronics cooling, cell-phone amplifiers, servers, power supplies, laser applications, etc.
