These Delavan 5800 Series PowerFLO Diaphragm Pumps replace the FIMCO spray pumps used on FIMCO ATV, Utility and Spot Sprayers. They are widely used in fluid transfer applications, as well as agricultural spraying applications.

Delavan PowerFlo 5800 Series are 5 chamber diaphragm pump and 12-volt DC motor combinations. The motors are permanent-magnet, totally enclosed and non-ventilated. They have priming capabilities of 14' (4.3 m).

Each of the Delavan PowerFlo Pumps we have listed here – 5850-111E and 5850-201E – have 12 V DC motors, Santoprene diaphragms, Viton valves and 1/2" (13 mm) FNPT ports. The housings are polypropylene and the fasteners are stainless steel. The Delavan 5850-111E is a bypass pump, while the 5850-201E is a demand pump and includes a pressure demand switch which only operates when liquid flow is required.

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. 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 for this purpose (see Related Products).
If you need to run either of these pumps continuously, we recommend running them at 40 psi (2.8 bar) or lower. Refer to the Heat Rise Chart (above).
