Omega PHP-600 Series


More details

The PHP-600 series pumps have been designed to meet the ever-changing needs of industry. To accommodate diverse applications, the pumps can be easily mounted anywhere in your plant with a broad, flat base and mounting holes for tank, shelf or floor mounting (horizontal). The rear of the pump housing also provides mounting holes to facilitate vertical mounting; wall, tank or machine. With the pump valve assembly and unit controls both located on the front of the pump, there is never a problem with installation or flow adjustments.
The PHP-600 series pumps are equipped with a single control for pump output. The external Flow Rate Control (potentiometer) on the face of the pump allows you to adjust the percentage of flow from 0 to 100% of the pump’s rated capacity. This feature eliminates the need to worry about stroke lengths and power settings. An LED indicator lights up each time a stroke begins. This allows the user to assess the stroke rate from a distance.
The PHP-600 series pumps have been manufactured with the highest level of mechanical precision from materials chosen for their inherent ability to resist the effects of most aggressive chemicals. When you select a PHP-600 series pump you are eliminating the time consuming effort involved in picking the right material for your application. The PHP-600 series pumps are supplied with the highest quality material as standard equipment, not optional. The diaphragm utilizes one-piece construction of PTFE, which unlike conventional laminated diaphragms will stand up to the test of time and wear. Ball valves are constructed in glass. The pump head, and O-rings are all made of PTFE or Kynar which offer unsurpassed resistance to the chemicals in your industry.
The PHP-600 series pumps are completely sealed during assembly and offer IP65 protection against splashes and spills providing excellent protection even in hostile environments. The fiber-reinforced polypropylene housing stands up to most aggressive chemicals while offering superior strength under tough industrial conditions.
The PHP-600 series positive displacement solenoid driven pumps use a minimum number of moving parts, therefore reducing the chance of mechanical failure. Part wear and oiling associated with motor driven pumps (ball-bearings, gear drives and cams) are not present in these pumps. The PHP-600 series pumps are more accurate than standard pumps with the positive displacement design ensuring each stroke is identical to the strokes before and after it, thus keeping the flow rate constant.
A wide range of The PHP-600 series pumps with different dosing capacities is available for your specific dosing needs. Each pump is supplied with discharge and suction valves. Polyethylene tubing, injection fittings, ceramic weights and replacement parts are also available.
