QP-2TZ — GENERAL INFORMATION

APPLICATION

QP-2TZ Trash Pump

The

is designed to be used for dewatering applications. Both the suction and discharge ports on the QP-2TZ trash pump use a 2-inch diameter opening, which allows the pump to pump at a rate of approximately 211 gallons/ minute (gpm) or 800 liters/minute (lpm).

Trash or self-priming pumps are designed to purge air from the suction line and create a partial vacuum in the pump body. The reduced atmospheric pressure inside the pump allows water to flow through the suction line and into the pump body. The centrifugal force created by the rotating impeller pressurizes the

Elevation

Higher elevations will effect the performance of the pump. Due to less atmospheric pressure at higher altitudes, pumps DO NOT have the priming ability that they have at sea level. This is due to the “thinner air” or lack of oxygen at higher altitudes.

A general rule of thumb is that for every 1,000 feet of elevation above sea level a pump will lose one foot of priming ability.

For example, in Flagstaff, Arizona where the elevation is approximately 7,000 feet, the pump would have a suction lift of 25 feet rather than the 18 feet at sea level. Table 3 shows suction lift at various elevations.

This pump is intended to be used for dewatering applications and is capable of suction lifts up to 25 feet at sea level. For optimal suction lift performance, keep the suction hose or line as short as possible. In general, always place the pump as close to the water as possible.

QP-2TZ — PUMP COMPONENTS

Figure 2 shows a typical application using the QP-2TZ Trash 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 1.0 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. QP-2TZ Pump Application

1. Pump – The model QP-2TZ is a 2-inch trash pump used in general dewatering applications. Typical dewatering applications consist of manholes, septic tanks, fast and slow seepage ditch water, silt water, mud water and muck water.

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.

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 this 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.

To perform the pump vacuum test do the following:

1. Remove the pump fill cap (Figure 2), and fill the pump with water.

2. Start the engine as outlined in the initial start-up section, and wait for the pump to begin pumping.

3. As shown in Figure 13, place a water hose inside the discharge opening of the pump, and turn on the water. This flow of water into the discharge opening will pump from running dry.

4. Place the pump suction (inlet) opening (Figure 13) with the vacuum gauge facing upwards. It may be necessary to apply a small amount of water around the rubber seal of the vacuum tester to make a good suction fit.

5. Check and make sure that there are no air leaks between the vacuum tester and the inlet port on the pump. If air leaks are present reset vacuum tester.

6. Run the pump for a few minutes while monitoring the vacuum gauge. If the gauge indicates a reading between -25 and

-20 in. Hg. (inches of mercury), then it can be assumed that the pump is working correctly.

QP-2TZ — PREPARATION FOR LONG -TERM STORAGE

Pump Storage

For storage of the pump for over 30 days, the following is required:

Drain the fuel tank completely.

Run the engine for about 3 minutes and then stop.

Stop the engine. Drain the engine crankcase oil while the engine is still warm. Fill engine crankcase with fresh oil.

Pull the recoil starter grip (Figure 17) 2 or 3 times. DO NOT start the engine.

Figure 17. Recoil Starter Grip

Pull the recoil starter grip slowly. STOP when it feels tight. This closes the intake and exhaust valves (compression position) , and helps prevents rust from forming.

Wipe any oil or dirt that may have accumulated on the engine.

Remove the drain plug from the pump and drain out any water left in the housing.

Remove the pump cover and clean the inside of pump housing. Coat the inside of pump housing with a light film of oil to reduce corrosion. A spray can of oil works well for this application.

Cover suction and discharge ports with duct tape to prevent any foreign matter from falling into pump.

Cover pump and engine with plastic covering or equivalent and store in a clean, dry place.

To protect the water cooled-seals, place one-half pint of lubricating oil (new or used) through the discharge opening on the pump and crank the engine several times. This will prevent excessive corrosion and also keep the mechanical seal lubricated.
