A Grinder Pump is a centrifugal pump equipped with a grinder system at the pump inlet, which cuts larger particles and fibres into a homogeneous wastewater mass. Some pumps have a specific pumping zone, and they can only operate within a specific pressure range. It also has a tough hermetically sealed thermal overload for optimum motor protection. A float switch usually controls the operation, turning the pump on once the wastewater in the basin reaches a certain level. This will slice all the materials into smaller pieces and use higher pressure to transport all the waste to the septic tank or system. 2) Pump must be capable of providing the minimum required GPM for pipe size, Figure “C”, at the calculated TDH #10 . This decision should be based on your intended application. A grinder pump is designed to handle the flush of human waste, toilet paper and sanitary napkins such as feminine hygiene products (Sanibest Pro, Sanigrind Pro, Sanicubic 1 and Sanicubic 2). 2.0 HP Sewage Grinder pumps also require a minimum of 20 to 30 feet of head pressure in order to operate correctly. What's a grinder pump?

This type of grinder pump allows for higher pumping heights as the material is squeezed inside the rubber stator pumping the wastewater through the pump and out of the basin. Non-corroding 316 stainless steel is the material of the impeller. This is all made possible by the V-shape working in conjunction with a specifically designed rotary cutter. Pumps, on the other hand, use a slightly different description of "gallons per minute" or GPM. Need more options? Semi-positive displacement grinders are typically used in applications that require higher discharge heights, typically in the 140 feet of lift range, sometime higher. The friction loss in the supply pipe also includes the unions or other fittings that connect to the pressure manifold. The second component of this calculation is the minimum pressure delivered at each orifice. That volume is the amount of liquid needed to fill the laterals and is set by the dose volume to the laterals.
