GENERAL PURPOSE
BP SERIES
The general purpose diaphragm pump range is suitable for all low and medium pressure boom and spot spraying applications.
This range of pumps operates in the pressure range of 0-2000kpa producing flows from 20 l/min to 305 l/min.
Wide spread uses include the application of herbicides, fungicides and pesticides in vegetable and pastoral situations.
SELECTA diaphragm pumps are widely used throughout Australia for orchard, vegetable, broadacre spraying and other agricultural and industrial applications.
The oil backed diaphragm design offers the versatility of high pressure, and long life. All moving parts are immersed in a complete oil bath to provide total protection against chemical corrosion.
This lubricating oil is used to also supply hydraulic pressure to draw the diaphragm on the delivery or pressure stroke. All other parts in contact with the spray are constructed of corrosion resistant materials. The only moving part in contact with chemicals is the diaphragm.

HIGH PRESSURE
MP, P & APS SERIES.
The MP, P & APS series diaphragm pumps are designed for high pressure handgun and boom spraying. This range of pumps operate in the 0-4000kpa pressure range, The higher pressure allows these pumps to cope with extended hose lengths and hose reels commonly used in difficult terrain whilst retaining high pressure at hose gun end.
* Through shaft models as indicated allow for secondary point of operation e.g. To drive agitator, blower fan in orchard applications.

All SELECTA diaphragm pumps are built for 540rpm operation, self priming and designed so no special tools are required for service. Tough and reliable they run dry without risk of damage.
All pumps are supplied with appropriate hose connections, mounting base plate, 1 3/8" six splined shaft and control unit as required. Some models are available with keyed shaft.

PTO Cover shown on BP265/20 is standard on ALL pumps.
