• Diaphragm Pump
• Max output varies: 0.6 - 6.3 GPH
• Max pressure varies: 30 - 150 PSI

Walchem's EZ pumps possess the following features:

• High chemical resistance
• Low power consumption (20-22 watts)
• Manual operation (on/off/speed control)
• Optional timer control
• Solenoid drive
• 1 - 360 strokes/min. (settable)

These pumps are more precise than their tube/peristaltic pump counterparts and have better repeatability as well. The diaphragms are Teflon® faced and are therefore compatible with many chemicals.

The V-5 is a heavy duty piston metering pump built for minimum maintenance from quality materials. The pump end of the unit utilizes a precision inline machined casting for minimum wear and strength. The pump is driven by a continuous duty oil filled speed reducer which is available in several ratios for the required stroking rate. The speed reducer will accept any 1750 RPM, 1/2 HP, 56 frame motor with foot mount base, making for limitless options with regard to motor enclosure and supply characteristics. The wet end of the pump is precision machined and utilizes a ground stainless steel piston to minimize packing wear. The check valves are of the double ball check design to insure accurate metering. Various piston sizes are available to give a wide range of volume outputs. The output of the pump is varied from zero to maximum by manually adjusting the piston stroke length or, automatically with a variable speed motor and controller option. All the various piston head sizes are interchangeable which makes application changes in the field simple. All V-5 pumps are supplied with a pressure relief valve for each pump head.

The wet end of the pump is precision machined and utilizes a ground stainless steel piston to minimize packing wear. The check valves are of the double ball check design to insure accurate metering. Various piston sizes are available to give a wide range of volume outputs. The output of the pump is varied from zero to maximum by manually adjusting the piston stroke length or, automatically with a variable speed motor and controller option. All the various piston head sizes are interchangeable which makes application changes in the field simple. All V-10 pumps are supplied with a pressure relief valve for each pump head. A vertical motor option is available - call or email us for details.
