Water Injection System
Pre-Filter
Spin down type with washable cartridge in clear plastic housing and plastic ball
valve for flushing.
Supply Filter Replaceable cartridge in plastic housing with air bleed button.
Water Pressure Switch
Senses for water pressure after filter and turns on when pressure is over 20–28 psi
and turns off when pressure drops below 7–13 psi.
Pump
Pump is a Toro exclusive design (patent pending) with cast stainless steel head
and 3 piston plungers. Vee packing seals and Kevlar guides. Forged crankshaft
with plasma sprayed ceramic on stainless steel plungers and cast iron connecting
rods. Nominal performance is 4 gpm @ 5000 psi with 1400 RPM input.
Accumulator
Toro exclusive design with low charge pressure sensor, nitrogen gas charged to a
maximum of 2500psi.
Cam and Gearbox
Reduction gear drive for cam that actuates main water valve. Roller cam follower
rides on cam specifically designed (patent pending) to control water injection at 5.3
cycles per second (320 RPM) and store energy in accumulator between injections.
Cast iron case also serves as 4 quart hydraulic reservoir.
Valve
Cast stainless steel valve body functions as mounting base for accumulator,
gearbox, and manifold outlet. All high pressure water flows in and out through the
valve body. Pressure balanced valve spool with floating (patent pending), hardened
stainless seat aligns during assembly. Bleed valve in base allows for bleed-off of
high pressure and drain down for cold weather storage. Bolted flanges and
polyurethane o-rings mate all components to valve body.
Rollers
Pivoting aluminum rollers uniformly smooth the turf and provide protection from the
nozzle discharge. Adjustable flow (0–3 gpm) spray wash system with 6 flood tip
nozzles maintain clean rollers.
Pressure Relief Valve
Circle Seal Controls poppet-type valve preset to 5000 psi with corrosion resistant
stainless and brass materials.
Manifold and Nozzles
Extruded stainless steel manifold with 11 flanged nozzle extensions containing
check valves and hardened stainless discharge orifice. Check valves may be
reversed in housing to block unused nozzles.
