Features

• Triplex Uniflow design provides a smooth, low-pulsation flow with strong suction capabilities.
• Hard chrome-plated 304S cylinders (optional 316SS) and sleeves provide long life with mild liquids within a range of 5-9 PH.
• Optimal 316 stainless steel manifolds for added strength and corrosion resistance.
• Optimal FPM elastomers for liquid compatibility.
• Patented stepped piston rod with stainless steel sleeves provides a durable wear surface and easy wet-end servicing.
• Cylinder and sleeve wear surfaces are hard chrome-plated 304 stainless steel for longer service life.
• Manifolds are of high tensile strength chrome-plated brass or 316 stainless steel for special corrosion resistance.
• 100% wet cup/seal design adds to service life by allowing pumped liquids to cool and lubricate the elastomers on both sides.
• 304 stainless steel valves, seats, and springs provide corrosion-resistance, ultimate seating and extended life.
• Mechanically actuated inlet valves provide strong lift and easy prime.

Operating Limits

• Liquid pH Range (for 304S cylinders): 5-9 PH
• Maximum Liquid Temperature: 160°F (71°C)
• Inlet Pressure Range: –8.5 to +40 psi (–0.6 to +2.8 bar)

Electrical

The required horsepower (H.P.) can be determined by the formula: (gpm x psi) / 1460. The document also provides a table for "ELECTRIC HORSEPOWER REQUIREMENTS" based on flow and pressure. See the official PDF for exact tabulated values.

Materials of Construction (Selected Components)

• Cylinders: Hard chrome-plated 304S (optional 316SS), or unchromed 304SS.
• Sleeves: Hard chrome-plated 304SS (optional 316SS), or unchromed 304SS.
• Manifolds: Chrome-plated brass or 316 stainless steel (optional).
• Valves, Seats, Springs: 304 stainless steel.
• Elastomers: FPM (Fluorocarbon), NBR (Medium Nitrile/Buna-N), PTFE (Pure Polytetrafluoroethylene).

Important Notes

• All High Pressure Systems require a primary pressure regulating device (e.g., regulator, unloader) and a secondary pressure relief device (e.g., pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to pump or property.
• C.A.T. (Captive Acceleration Tube) is highly recommended for pressurized inlet, R.O. (Reverse Osmosis), and Industrial applications.
