MQ-D206H— PUMP COMPONENTS

Figure 2 shows a typical application using the MQ-D206H diaphragm pump. Please note that this pump is intended for the removal of clean water and water containing some debris and solids. Maximum size of solids should not exceed 1 inch (25 mm) in diameter. DO NOT set strainer on bottom of water bed. Placing the strainer above the water bed will prevent the pump from drawing in excessive amounts of sand and foreign debris.

Figure 2. MQ-D206HPump Application

1. Pump – The MQ-D206His a 2-inch diaphragm pump and is used in general de-watering applications. Typical dewatering applications consist of cleaning out cesspools and septic tanks, draining slow seepage from small excavations, trenches and construction sites, or pumping out industrial waste.

2. Fill Cap – Prior to operation, the pump casing should be filled with water.Remove this cap to add water to the pump. After the initial prime, a sufficient amount of water will be retained in the casing so that the operator will not need to re-prime later.

If the casing is dry or has insufficient water, the pump will have difficulty in priming which could lead to premature mechanical seal wear thus causing damage to the pump.

3. Discharge Port – Connect a 2-inch discharge hose to this port. Use two worm clamps to secure the hose.

4. Worm Clamp – Used to secure the hose to the inlet and outlet ports on the pump. Use two clamps to secure the hose on the inlet side of the pump.

5. Discharge Hose – Connect a flexible rubber hose to the discharge port on the pump. Make sure that the hose lays flat and is not kinked. Use only recommended type discharge hose. Contact Multiquip parts department for ordering information.

6. Suction Port – Connect a 2-inch inlet hose to this port. Use two worm clamps to secure the hose.

7. Suction Hose – Connect a flexible rubber hose to the suction port on the pump. Make sure that the hose lays flat and is not kinked. Use only recommended type suction hose. Contact Multiquip parts department for ordering information

8. Strainer – Always attach a strainer to bottom side of the suction hose to prevent large objects and debris from entering the pump. Strainer should be positioned so that it will remain completely under water.Running the pump with the strainer above water for long periods can damage pump.

9. Transmission Oil Fill Plug – Remove this plug to add SAE 80/90 EP gear oil to the transmission.Transmission oil capacity is 1-1/4 pints (550 ml.).

10. Connecting Rod Grease Access Hole – Grease connecting rod bearing through this access hole. Grease connecting rod bearing every 25 hours of operation.
