These pumps are constructed with a multi-piston design to produce plenty of pressure to help ensure complete and efficient coverage for all your spraying needs. Pressure and output are designed for optimum performance on small to medium-sized sprayers. Common uses include spray applications of lawn and garden, turf and trees; metering applications for fertigation and acid descaling.

  • Equipped with a variety of features that help to improve longevity:
  • Crown shaped pistons conforms to diaphragm at pressure stroke to help prevent wear
  • Valves are made of corrosion-resistant 316 stainless steel
  • Spherical profiled valve poppet designed to deliver higher volumetric efficiencies
  • Less piston stroke for longer diaphragm life
  • Equipped with a needle bearing on the connecting rods to ensure pump longevity.
  • Easy access valve caps
  • Exclusive to model 9915-DP503
  • Chemical resistance polypropylene overmolded aluminum heads
  • Hardened Bioxistop aluminum heads, manifold, and case helps preserve pump from white oxidation of aluminum that comes in contact with water
  • Double piston rings – helps maintain oil pressure to hydrodynamically support the diaphragm through the pressure cycle
  • Polypropylene pump models are ideal for highly acidic chemicals, such as N-pHURIC
  • Pump shaft rotation: CW and CCW
  • Mounting base included

Product Components

9915-DP252GRGI
  1. Connecting rods utilize a roller bearing on the crankshaft to ensure ultimate reliability and longevity.
  2. Thermal treatment on connecting rod rings provides wear resistance and long-life operation.
  3. Piston sleeves in cast iron and pre-set pistons deliver high volumetric efficiencies.
  4. Pump Shaft oversized ball bearings to help extend pump life.
  5. Double body head in polypropylene incorporating a die-cast aluminum core.
  6. Separate and replaceable suction and pressure circuits.
  7. Check valves to be overhauled easily, with little maintenance.
  8. Easier in-out system: rapid and accurate oil filling and longer diaphragm life.
  9. Gearbox with helical teeth, which ensures superior reliability and is noiseless.
  10. Pre-set diaphragm bolt and washer made up of 316 stainless steel specially selected for chemical resistance and longer operation life.
  11. Oil sight glass on the opposite side of the motor to provide easy reading of oil level.
  12. Diaphragms are designed to handle chemicals and never lose form.
9915-DP252 & DP302 Medium Operating Pressure Diaphragm Pump

9915-DP503

  1. Polypropylene heads with a die-cast aluminum core for exceptional chemical resistance and strength.
  2. All wet end hardware is made from 316 stainless steel for maximum chemical resistance.
  3. Dual piston rings ensure consistent support for the diaphragm.
  4. Pre-profiled DURAMAX diaphragms for reduced mechanical stress, accompanied by crowned pistons to reduce friction and extend life.
  5. Spherical shaped check valves, made from 316 stainless steel and polypropylene yields higher volumetric efficiency.
  6. Dual ball bearings to support the crankshaft, for withstanding higher loads.
