Submersible pump

1.1 Overview 

QYB-240R are designed to be compatible with 100% gasoline, Kerosene or diesel, and other liquid medium, Max. temperature lower than 40¡æ, Max. Specific Gravity 0.86g/cm³, Max. Viscosity 13 c.s.t (70 SSU) at 15¡æ, such as methanol, ethanol gasoline with 20% ETBE or MTBE. 

1.2 Features and Benefits:

QYB-240R pumping systems are designed to go the distance delivering smooth operation, with less maintenance and a long life. Features include: 

·        One small assembly contains all functional elements: check valve, air eliminator, expansion relief valve, syphon nozzle and venturi, syphon check valve and pressure test screw. 

• All models fit standard 4" NPT tank openings. 
• Bayonet-type electrical connector provides a safe explosion-proof electric disconnect without separating wires. 
• Pressure relief valve and check valve can be isolated to assist in pressure-testing the lines. 
• Tank-test port and line-test port are conveniently located on top of the discharge manifold. 
• Patented design feature directs any manifold assembly leakage into storage tank. 
• On-winding thermal over-current protector prevents premature motor failure. 
• Hydraulically balanced impellers "float" on the 16 spline shaft, providing a positive and evenly distributed drive.
