JD Diesel Water Pumps
JD (Jiang dong) diesel water pumps in Kenya by Grekkon Limited are of varying specifications for agricultural use in irrigation. This specifications are in regards to; the engine power, the head, and the flow rate. Our JD diesel water pumps consist of a diesel engine, and a horizontal single-suction, single-stage, centrifugal water pump. The water pump is made from cast iron
The water pump. It is rated by inlet/ outlet pipe size, head, and flow rate
The engine. It is rated in horsepower (Hp). The higher the HP, the more powerful it is
JD Diesel Water Pumps Characteristics
- high efficiency
- wide performance range
- safe and stable operation
- long service life because the cast iron impeller and volute reduce vibration and wear on the mechanical seal and engine
- convenient installation and maintenance
- can channel hot water, abrasive or corrosive liquids by changing the material of the water pump’s flow-through components, the form of the seal and adding a cooling system
Working Principal
After the start, the impeller rotates rapidly so that the water in the impeller channel flows towards the volute. During this time, a vacuum is formed in the inlet, and water flows from the suction pipe to the pump through the impeller channel
The right most critical terms when identifying the right pump performance is water volume and the lift/ head. Generally, a trade -off occurs between head and flow with an increase in one causing a decrease in the other and vice versa. Head refers to the gains or losses in pressure caused by gravity and friction as flows through the system. The lift is the vertical distance from the water line to the center line of the impeller
The greater the lift and the water volume required, the larger the engine power. For instance, to achieve a flow rate of 80 cubic litres per hour, at a head of 100M, then the engine power must be from 22Hp and above
