ZDB-A Automatic Cold-hot Water Self-priming Pump
YANGCHUN Pump Industry ZDB-A Automatic Hot and Cold Water Self-Priming Pump 10 Floors Residential Water Delivery 230V 3/2hp
ZDB automatic cold-hot water self-priming pump(called as pump below for short) is formed by copper winding motor, water pump and sealing. The motor is single phase asynchronous type. The impeller is vortex type structure providing high lift.
The pump is designed with self-priming function. At the first when using the pump, clean water shall be injected into the pump. After the first time of using, no more water injection is required.
The pump is equipped with automatic control system. When the valve is opened, the pump will be started. When the pump is closed, the pump will be shut down automatically. No manual power switching is required. Convenient, low energy consumption and high efficiency.
Scientific hydraulic design, reasonable structure layout, low vibration and noise, stable operation.
A grade high quality beam pressure tank, low switch using frequency, high product service life.
Electrophoresis anti-rust processed cast iron pump body and connection
304 stainless pump body and the area connecting runner prevent the impeller from being stocked when the pump is not used for a long period of time.
304 stainless steel welded spindle
High quality 59 copper impeller, the impeller blades are arranged in radial direction.
Copper motor winding
Single phase with inner overheat protection device
Protection level: IPX4
The pump is an ideal household water pump with high efficiency and low energy consumption. It can be widely applied for family water supply, well water drawing, tap water pipe pressure charging, garden irrigation, and especially for pressure charging on solar energy pipe of water heater with low water pressure in order to avoid unstable temperature of the water supplied.
The pump can be continuously functional under the conditions below
Medium temperature shall be within +90℃.
PH value of media shall be around 6.5-8.5.
Maximum solid impurity size no more than 0.1%, particle size no more than 0.1mm.
Power source frequency 50Hz, single phase alternating voltage 220V, tri-phase alternating voltage 380V, voltage fluctuation ranges ±10% of rated value.
When environment temperature is below 0℃, low temperature protection shall be applied. Drainage screw at bottom of the pump shall be loosen and the water inside the pump shall be drained in order to prevent the pump body from being frost-cracked when the pump is not working (automatic type shall ensure that there is no water leakage on pipes).
Instruction for Applying in Different Floors
The photos attached below are: the top floor uses 1-2 taps, and the flow of each tap is 0.8m³/h. Independent water usage height shall be less than 8 meters. Suction height can be accumulated. The pump is suggested to be assembled within water depth of 6 meters. Pipe lose has to be considered and one elbow can be considered as 1 meter of pressure loss.
