Comet APS51 Diaphragm Pump

Note: Shaft and regulator not included

The Comet APS51 Diaphragm Pump is the ideal pump of choice for professionals and agriculturalists alike when they need a high pressure pump intended for a range of spraying applications, such as weed control, pest control, medium-height tree and shrub spraying, medium to large dimension crop spraying, lawn care, and more.

Many of the pump's internal components consist of anodized aluminum, and when you combine that with effective stainless steel check valves that provide excellent chemical resistance, the Comet APS51 will have no troubles handling and pumping common agricultural chemicals, including herbicides, pesticides, fertilizers, de-icing materials, and more, providing long lasting durability that goes unmatched in the field.

This Comet APS51 high pressure, three-diaphragm pump includes a 6 hole flange shaft to allow for a connection to a gas engine with either a 3/4" or 1" shaft.

Take note that every diaphragm pump requires a pressure regulator. We offer regulator recommendations for your Comet APS51 below.
