Operating Limits

The general product performance range is:

• Flow: 0.13 to 240 gpm (0.49 to 908 lpm)
• Pressure: 100 to 10,000 psi (6.9 to 689 bar)
• RPM: 100 to 3450

• Flow range: 0.68 to 30 gpm (2.6 to 113.5 lpm)

Mechanical / Hydraulic

Key construction features:

• Crankshaft: Chrome-moly for strength and surface hardness.
• Piston Rod: Patented stepped piston rod with hard chrome-plated sleeve.
• Plungers: Precision-polished, solid ceramic.
• Seals: Specially formulated high pressure and low pressure seals.
• Wet Cup/Seal Design: 100% wet cup/seal design for cooling and lubrication.
• Valves, Seats, Springs: Stainless steel for corrosion-resistance and positive seating.
• Plunger Rods (SF series): High strength stainless steel with 360° supported crosshead.
• Connecting Rods: Matched oversized, high strength material.
• Bearings: Oversized ball bearings or tapered roller bearings.
• Crankcase: High strength, lightweight die cast aluminum with splash oil design.
• XP Series Pumps: Utilize a flow-through ceramic plunger design.
• SF Series Pumps: Utilize a flow-through ceramic plunger design.

Available drive types include:

• Electric
• Engine
• Hydraulic
• Pneumatic

Drive packages offered:

• Belt
• Direct Drive
• Gearbox
• Flex Coupling/Bell Housing
• Clutch

Pump rotation:

• Forward rotation (towards the manifold) is recommended for optimum lubrication.
• Reverse rotation is acceptable if the crankcase oil is above the red dot in the oil gauge.

Commonly Used Formulas for Hydraulic Torque:

• Hydraulic Torque (ft. lbs.) Required = (gpm x psi) / (rpm x 3.6)

Electrical

Commonly Used Formulas for Electric Power:

• Required Electric Brake HP = (gpm x psi) / 1460 (Standard 85% Overall Efficiency)
• HP Calculation (1CX Series only) = (GPM x PSI) / 1060

• 1/4 hp, 115/230 V, 60Hz, 1ph, 1750 rpm, 12 inch leads
• 1/2 hp, 115/230 V, 60Hz, 1ph, 1750 rpm, 12 inch leads
• 1/2 hp, 115/230 V, 60Hz, 1ph, 1750 rpm, terminal box
• 1/2 hp, 115/230 V, 50Hz, 1ph, 1450 rpm, terminal box

Centrifugal Pumps with integral motors and seals:

• Submersible pumps: 0.3 to 1.0 hp
• Self-priming motorized units with TEFC 56J NEMA motor: 1.0 to 2.0 hp
• End-suction motorized units with TEFC 213/215JM NEMA motor: 0.5 to 1.0 hp

Feed Water / Product Water

For Centrifugal Pumps, typical fluids pumped include fresh water, semi-contaminated water, or liquids with some suspended solids. Liquid CO₂ pumps are designed for liquid CO₂ applications, which require handling low lubricity and low temperature.
