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
  • 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
  • Pump shaft rotation: CW and CCW
  • Mounting base included

Product Components

9915-DP252 and 9915-DP302

  1. Motor type kinematic motion with crankshaft connecting rods-bearing-pistons system.
  2. Thermal treatment on connecting rod rings provide wear resistance and long life operation.
  3. Piston sleeves in cast iron and pre-set piston delivering 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 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-DP503

  1. Heads and manifolds are made up of strengthened polypropylene to ensure the best compatibility with chemicals.
  2. Oil tank fitted with a matched diaphragm to ensure correct oil level.
  3. Manifolds are separate from crankcase for complete protection of the kinematic mechanism in an oil bath.
  4. Shorter crankshaft stroke reduces the stress on the diaphragms helping to increase pump life.
  5. Spherical profiled check valve design provides a more positive contact at closure to help increase overall volumetric efficiencies.
  6. Heat exchanger reduces pump oil operating temperature to help extend pump life.
