PEARL JSCH SERIES - HIGH HEAD - STAINLESS STEEL SHALLOW WELL SELF PRIMING JET PUMP - 1.5 HP - 230 Volt JSCQ verses JSCH JSCQ SERIES - Higher flow rates - Standard Pressure Range ( 30 to 50 psi ) JSCH SERIES - High Head - Lower Flow Rates - Higher Pressure Range ( 40 to 70 psi ) Standard Features and Highlights • An exclusive diffuser design with flow control device provides for compact construction, fast self-priming capability and low noise • Reliable with new design features the JSCH/JSCQ is more robust and forgiving when temporary abnormal operating conditions may exist • The JSCH/JSCQ is smaller than conventional pumps of a similar type, allowing for installation in restricted spaces and providing for easier retrofit applications • Fast air evacuation reduces the risk of air-pockets developing at the mechanical seal preventing the danger of seal failure due to a lack of flushing and cooling • The new diffuser and flow control device guide the fluid from the impeller into the central part of the pump casing, reducing turbulence and velocity, with effective use of the surrounding liquid in dampening the noise of flow • Pump body made of stainless steel 304 • Impeller: Low lead brass • Includes: Dry pressure gauge in metal Typical Application & Use • For drawing water out of a well • For lifting water containing air or other gases • For increasing water pressure from flooded suction applications • As pressure boosting pump for central water systems with low pressure (follow local specifications if increasing network pressure) • For garden use • For clean liquids or slightly dirty surface water • For washing with a jet of water Performance Ratings ( Optimum Ranges ) Recommend to use with less than 22 ft suction lift • 5 Ft Lift @ 40 PSI : 25.2 GPM • 5 Ft Lift @ 50 PSI : 18.6 GPM • 5 Ft Lift @ 60 PSI : 12.0 GPM • 5 Ft Lift @ 70 PSI : 5.9 GPM *Max Shut-Off Pressure: 82 psi • 10 Ft Lift @ 40 PSI : 24.4 GPM • 10 Ft Lift @ 50 PSI : 17.8 GPM • 10 Ft Lift @ 60 PSI : 11.2 GPM • 10 Ft Lift @ 70 PSI : 5.1 GPM *Max Shut-Off Pressure: 80 psi • 15 Ft Lift @ 40 PSI : 22.7 GPM • 15 Ft Lift @ 50 PSI : 16.0 GPM • 15 Ft Lift @ 60 PSI : 9.5 GPM • 15 Ft Lift @ 70 PSI : 3.7 GPM *Max Shut-Off Pressure: 78 psi • 20 Ft Lift @ 40 PSI : 21.5 GPM • 20 Ft Lift @ 50 PSI : 14.9 GPM • 20 Ft Lift @ 60 PSI : 8.5 GPM • 20 Ft Lift @ 70 PSI : 2.8 GPM *Max Shut-Off Pressure: 75 psi Operating Conditions • Liquid temperature: 32 °F to 95 °F • Ambient temperature up to 104 °F • Maximum permissible pressure in the pump casing: 116 psi • Continuous duty Motor Information • 2-pole induction motor, 60 Hz (n ≈ 3450 rpm) • Single-phase 230 V • Capacitor inside the terminal box • Insulation class F • Protection IP 44 Pump Construction • Close-coupled self-priming shallow-well jet pump with built-in ejector • A high-quality pump for domestic water supply • Designed with environmental considerations, featuring a stainless steel casing,brass alloy impeller with minimal use of plastic materials • Connections: threaded ports NPT Material of Construction • Pump Casing: Cr-Ni steel 1.4301 EN 10088 (AISI 304) • Casing Cover: Cr-Ni steel 1.4301 EN 10088 (AISI 304) • Impeller: Brass CW510L (lead free public LAW 111-380) • Wear Ring Impeller-Diffuser: Cr-Ni steel 1.4301 EN 10088 (AISI 304) • Diffuser: PPO-GF20 (Noryl) • Ejector: PPO-GF20 (Noryl) • Shaft: Chrome Steel 1.4104 EN 10088 (AISI 304), Cr-Ni steel 1.4305 EN 10088 (AISI 303) for JSC(H) 15 • Mechanical Seal: Carbon - Ceramic - NBR
