Items NOT INCLUDED with your pump that you may need: Check out the accessories for this pump on the right hand side of the page! They can help keep your pump running properly!
The PUMP GUARD will 'dump' any water above 145 degrees F. before it reaches your pump (saving you the trouble of rebuilding your pump)
PRESSURE REGULATOR / UNLOADER - if we list one to the right of the pump this is the model we suggest you use with your pump. Other models with different features like adjustable or fixed and with / without chemical injector are available.
The INLET WATER FILTER will catch most small debris before it enters your pump
The EZ-START VALVE will remove the pressure on your motor when you first start your pressure washer, this item eliminates you pulling your trigger on your pressure washer gun when starting your pressure washer
The PRESSURE GAUGE KIT allows you to monitor what pressure you are operating your pump at! This is very important when you are cleaning delicate items like decks, fences and cars! It also helps you diagnose pressure problems with your pump!
PUMP OIL, you can never have enough on hand! Many pumps ship with oil already in them. But you should always have a bottle on hand so you can change your pump oil according to the manufacturers instruction.

Features
- Manifold:
- Forged Brass: Strength and no porosity equals long life. Higher hydrostatic pressures, safety and performance.
- Inlet and Discharge Ports: Heavy bosses for added strength.
- Offset Discharge Ports: High efficiency, smooth flow.
- Bolts: Eight bolts, 6mm, grade 12.9.
- Valves:
- Ultra Form Cages: Durability, strength and long life.
- Poppets, Seat and Spring: 303 and 400 series stainless steel.
- Valve Caps: Machined brass – greater strength.
- Packing and Plungers:
- High Pressure Packing: “V” style (D-1) Buna-N (cotton duct weave base) strong and tightens under load.
- Low Pressure Seals: “U” cup double lip Buna-N, good positive seal.
- Support Guides: Machined brass, two-piece construction to assure proper plunger alignment and to maximize packing and seal life.
- Plungers: Are a special aluminum oxide blend, solid ceramic for long life, strong durability and more resilient.
- Bearings:
- Oversized for maximum life and load disbursement, needle bearing on the drive side and ball on the non-drive side. Each bearing is held in position on the crankshaft and crankcase by snap rings. This assures positive alignment and centering of the connecting rods and crankshaft in relation to the crankcase, it also eliminates the crankshaft from floating.
- Crankcase: Precision die-cast, large cooling fins and anodized (for maximum heat dissipation).

- Valve Design: Each pump series has a valve design that optimizes its highest efficiency.
- Hot Water: High temperature kits are available to 180º F. Refer to breakdown
- Wet End Repair: Very simple no special tools are required.
- Mounting Bolt Pattern: Same on the top and bottom of the crankcase for simple drive side change.
- Design: Using advanced fluid handling design programs. Overall pump efficiency is increased.
