Delavan PowerFlo 7800 Series Diaphragm Pumps have 3 chambers and 12VDC motors. These positive displacement pumps are self priming, capable of being run dry and have demand or bypass mode. Priming capabilities of 14' and a maximum pressure of 60 psi.
The housings on the 7812-201, 7812-301, 7812-111 (which replaced the 7812-211), and 7802-201 PowerFlo Pumps are polypropylene, the valves are Viton®, Santoprene® diaphragms and stainless steel fasteners.
Demand Pumps require a balanced flow. Too small of a nozzle, whether on your spray gun or on your spray boom, may restrict the flow resulting in your Demand Pump shutting off. Demand pumps have a pressure demand switch that operates only when liquid flow is required. Bypass Pumps can be used in applications which would normally result in frequent stopping and starting of the motor. Pump models with an internal bypass are designed to pump at a high pressure with low flow rates.
We recommend using the AA122-1/2-PP Poly Line Strainer (see Related Products) to help eliminate contaminates from running through your Demand or Bypass Pump. Bypass Pumps require a Regulator, we recommend the 23120-1/2-PP Poly Regulator as well as the strainer.
