Vacuum pump

• maintenance free
• lubrication free

The EcoDry M piston vacuum pump is free of oil and hydrocarbons, yet has the same vacuum performance as oil-sealed rotary vane pumps. Unlike scroll pumps, this model emits very few wear particles from the inlet that could interfere with sensitive analytical equipment such as electron microscopes. The pump has variable speeds of 750 to 1200 rpm, 15,000 hours of maintenance free operation, and runs with any 50/60 Hz input power between 90 and 264V. Even after long periods of operation, the piston coating and specially designed valves and gas passages result in nearly undetectable wear particles at the inlet of the pump. The variable speed motor can run at lower speeds to save energy, reduce vibration and sound levels, and extend the life of the pump. Leybold Vacuum Products, Export, PA www.rsleads.com/304df-125

Positive displacement pump
This line of positive displacement circumferential piston pumps has capacities to 150 gpm and pressure capability up to 200 psi. All models have 4-way mounting and the three smallest sizes have a stainless steel gearcase. Standard features include helical timing gears for higher torque and quieter operation, 17-4 PH stainless steel shafting and polyester epoxy blend powder coating. Wright Pump, Waukesha, WI www.rsleads.com/304df-126

Rotary vane pumps
These rotary vane pumps offer high intermittent pump capacity in a low profile, modular design. Reversible models are available. Pressure and vacuum sides are switched by reversing motor polarity — no additional valves are needed. Pumps can be operated at different voltages and controlled continuously via the distribution voltage. Vacuum levels of 600 to 800 mbar are achievable. Thomas Pumps & Compressors, Sheboygan, WI www.rsleads.com/304df-127

Flow indicator
Designed to enhance the company’s line of injector pumps, the Sight-Rite flow indicator can be used in any lubrication or process equipment that carries a pulse of fluid of less than 0.012 in.3. Each pulse of liquid cycled through the indicator activates a green LED light, permitting fluid verification. Rugged epoxy and acetal bodies resist chemicals and solvents. Oil-Rite Corporation, Manitowoc, WI www.rsleads.com/304df-128

Chemical transfer pump
Specifically designed for pulse-less fluid transfer at variable flow rates, the Variable-Flow chemical transfer pump operates with fluids with a viscosity up to 200 centipoises from 120 ml to 2.2 liters per min. The suction lift is 10 ft wet, and operating temperatures are -40° to 200°F. Barbed inlet/outlet ports use any type of tubing (nominal 3/16 in. ID). Control Co, Friendswood, TX www.rsleads.com/304df-129

Pulse-free metering pump
Designed for applications requiring extremely precise continuous pulse-free fluid flow, the QX series metering pump can be operated through a computer interface using the company’s PumpWorks software or through a touch screen front panel display. Flow rates, pressure and other operating parameters can be controlled. Maximum pressure ratings are 500, 1500 or 6000 psi. Quizix Inc, North Highlands, CA www.rsleads.com/304df-130

Dispense pump
The IDS 2000 dispense pump is intended for industrial process applications requiring maintenance-free, precision fluid control. The integrated pump and electronics are housed in a stainless steel enclosure and is suitable for wall mounting in process areas. Its CeramPump valve-less design has only one moving part — a rotating and reciprocating piston made of dimensionally stable, chemically resistant ceramics.

Peristaltic pumps
This brochure details the company’s custom peristaltic pumps for OEM engineers. Included are the 100 Series with versatile flow-speed range, the 300 series with flip-top pump head, 300 series for flow and medium flow applications, and the 500 series with twin roller, spring-loaded pump head. Also included is the company’s OEM speed control board for the 100, 300 and 400 series. Watson-Marlow Bredel, Wilmington, MA www.rsleads.com/304df-132

Micro annular gear pumps
This line of micro annular gear pumps offers very compact size, precise flow rate control and pulseless fluid delivery. Measurements are 13 mm dia. by 68 mm length. Tight flow rate control is available for pressures up to 1160 psi. High precision rotors dispense volumes as small as 0.25 µl and handle flow rates from 0.15 to 300 ml/min with ±1% accuracy. Micropump Inc, Vancouver, WA www.rsleads.com/304df-133

Rotary positive displacement pumps
Using gear and lobe principles, these rotary positive displacement pumps offer an alternative to centrifugal pumps in applications where system pressure or fluid viscosity fluctuates. Near-constant flow rates with minimal efficiency change are independent of alterations in pressure and viscosity. Viscosities of 28 SSU to 2 million SSU can be handled. Viking Pump, Cedar Falls, IA www.rsleads.com/304df-134

Feed verification
The Flow Checker oval gear meter mounts directly to the discharge of any of the company’s PZ, PZi4 or PZi8 pumps, and provides 1 pulse output for each 1 ml of liquid measured, thereby adding feed verification. The output can be connected to a controller or PLC. The PZi8 model pump displays instantaneous flow measurement on its LCD when connected to the Flow Checker. Neptune Chemical Pump Co Inc, Lansdale, PA www.rsleads.com/304df-135

Compact solenoid pumps
This line of manifold mountable inert solenoid pumps and valves offers a footprint as small as 0.5 in. for space-saving mounting. The efficient, locked-in threaded mounting collar design secures the pump or valve to the manifold port with hand-tightening to ensure an event load on the gasket seal for pressures up to 100 psi. Positioning the pump closer to the inlet minimizes internal volume. Bio-Chem Valve Inc, Boonton, NJ www.rsleads.com/304df-136

Compact metering pumps
The M-03 metering series pump provides maximum capacity of 3.0 gpm at 1750 rpm, maximum inlet pressure to 250 psi and pressure variable to 1200 psi. They provide linear flow throughout the pressure range, and offer accuracy and repeatability at lower cost than comparable conventional pumps. They can be close-coupled to 56C faced or metric motors or belt-driven, depending on application specifications. Wanner Engineering Inc, Minneapolis, MN www.rsleads.com/304df-137
