Frequently Asked Questions - DHY80E HYUNDAI

What type of fuel does the Hyundai DHY80E water pump use?

The Hyundai DHY80E uses diesel fuel. Always use clean, fresh diesel and allow a 25mm gap in the tank for fuel expansion.

How do I start the DHY80E water pump?

The pump has two starting methods: electric start (turn key switch clockwise) and recoil start (pull handle after moving decompression lever). Ensure fuel and oil levels are correct, and the stop/run lever is in RUN position.

What is the maximum total head of this pump?

The maximum total head is 25 meters (approximately 82 feet). The suction head should not exceed 6 meters (20 feet).

What type of oil should I use for the engine?

Use SAE30 mineral oil or SAE15W40 mineral oil. The engine oil capacity is 1.1 liters.

How often should I change the engine oil?

Change the engine oil after the first month or 20 hours of use, then every 6 months or 100 hours thereafter.

What should I do if the engine will not start?

Check the following: stop/run lever is in RUN position, fuel tank has diesel, battery is charged, and oil level is sufficient. Also check the air filter and fuel supply.

Can I use the DHY80E pump indoors?

No, the pump produces carbon monoxide (a colorless, odorless gas). Only use it outdoors in a well-ventilated area. Never use in homes, garages, tents, or vehicles.

How do I prime the pump before starting?

YOU MUST allow a 25mm gap between the fuel and the top of the fuel tank to allow for fuel expansion.

4.9 Refit the fuel filler cap securely.

5. OPERATION

What is head?

5.0 Head refers to the height of a column of water that can be delivered by the discharge of the pump.
5.1 Suction Head is the vertical distance between the centre of the pump and the surface of the liquid on the suction side of the pump. May also be referred to as 'suction lift'.
5.2 The atmospheric pressure of 14.7 psi at sea level limits suction head lift to less than approximately 26 feet for any pump.
5.3 Discharge Head is the vertical distance between the pumps discharge port and the point of discharge, which is the liquid surface if the hose is submerged or pumping into the bottom of a tank.
5.4 Total Head is the sum of the suction head value plus the discharge head value.
5.5 As water pumping height increases, pump output decreases. The length, type and size of the suction and discharge hoses can also significantly affect pump output.
5.6 It is important for the suction operation to be the shorter part of the total pumping action.

5.7 This will decrease priming time and improve pump performance by increasing the discharge head.
5.8 Suction head is a maximum of 25 feet and discharge head should be a maximum of 81 feet.
5.9 Total head cannot be more than 106 feet.

Pump Positioning

5.10 For best pump performance, locate the pump on a flat, level surface as close as possible (but avoiding soft edges) to the water to be pumped.
5.11 Secure the water pump to prevent it from tipping over.
5.12 Use hoses that are no longer than necessary.

NOTE

Direct the open end of the discharge hose away from property, electrical supply sources and any other equipment that you do not want to get wet.

5.13 This water pump is not for use in mobile equipment or marine applications.
5.14 DO NOT top the engine or equipment at an angle that may cause the fuel to spill.
5.15 Secure the water pump, loads from hoses may cause the machine to tip over.

Priming the Pump

NOTE

The improper treatment of the water pump can cause damage and shorten the pumps lifespan.

5.16 Be sure the priming chamber has been filled with water before starting NEVER run the pump without priming.
