Dorrco Diaphragm Pumps, Designed to prevent usual mechanical wear and to lower your costs, the Dorrco Diaphragm Pump is innovatively designed for more convenient operation.The Dorrco Diaphragm Pump has an extra heavy duty construction that makes it long-lasting, alleviating the potential costs of pump or part replacement. As a positive displacement diaphragm pump, it functions more smoothly, reducing friction to prevent common wear on parts.Many operations spend extra money on high-horsepower motors to power their pumps. The Dorrco Pump doesnt need a lot of horsepower to function well. It can perform with the energy from a standard electric motor.

• The W model is an extension of the VM, and is similar in certain ways. However, its differences allow for even more intense thickeners. The W model comes in 6 and 8inch
• The pumping methods differ between the VM and the W. The W pumps design permits slurry to fill the cavity below its diaphragm as the diaphragm is lifted. Then, when the diaphragm is lowered, the inlet opening is sealed. When the pressure builds up, the top valve opens in response
• Most heavy-duty pumps require motors with high horsepower to drive them. High horsepower motors are typically expensive and difficult to replace. The Dorrcos design allows its V-belt sheaves and gear train to effect all speed reduction. This enables a standard motor to drive the Dorrco Diaphragm Pump
• Adjustments have been made to the Dorrcos design to prevent the usual wear from friction and low-quality materials. All of the pumps bearings are anti-friction, ball type. Additionally, the castings are made of Meehanite, a semi-steel that endures longer than conventional cast iron. The diaphragm lasts longer as well because of a unique design that prevents excessive wear
