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℃, Max. Specific Gravity 0.86g/cm3, Max. Viscosity 13 c.s.t (70 SSU) at 15℃, 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.

INSTALLATION SAFETY NOTICES

\n \n \n

  

DANGER

  

This product operates in the highly combustible atmosphere of a gasoline storage tank. To protect yourself and others from serious injury, death, or substantial property damage, carefully read and follow all warnings and instructions in this manual.

 

  

DANGER

  

ALWAYS DISCONNECT and LOCK or TAG OUT the power before starting to service the pump.

 

3.1 ATTACHING THE UMP

\n \n

Figure 3.1 Attaching the UMP

 

1: Place the new gasket on the new UMP so that all the holes align.

Visually inspect the pigtail connector in the discharge head. Replace if damaged. Be certain the indexing tab of the pigtail is seated in the notch of the discharge head.

2: Lubricate the o-ring and pigtail with petroleum based jelly.

3: Align the UMP positioning dowel and boss with the proper holes in the discharge head and push the UMP into position using hand force only. The UMP should be snug against the discharge head prior to installing the UMP retaining bolts. 

4: Install the UMP retaining bolts and lock washers. Snug and then torque the bolts using a cross pattern. Torque to 7 ft-lb. (11 N•m).

3.2 INSTALLING THE PUMPENOTENOTICE

  

NOTICE

  

The product temperature must not exceed 105°F (41°C) because the thermal overload protectors in the submersible motors may trip.

1. Attach tubing to barbed fitting, secure with clamp.

2. Lay tubing beside column pipe. Cut off 1-3 inches (25-76 mm) above the discharge head.

3. Secure tube to column pipe with tie straps. Locate tie straps approximately 6 inches (152 mm) from packer, 6 inches (152 mm) from discharge head and middle of tubing.

4. Install the pump onto the riser pipe using thread sealant while making the proper alignment of the manifold and piping. Tighten the manifold until watertight.

3.3 CONDUIT BOX WIRING

1: Connect electrical conduit through approved fittings to conduit box.

2: Remove cover from conduit box.

3: Connect wires from power supply to wires in the conduit box. Install ground wire as shown if applicable. Replace cover, do not use thread sealant on dual box. Thread sealant required on single box.
