USE:
Type IZ pumps are the single-stage closed-couple centrifugal pump which draining for plant and city, water supplied for altitude supercharging, firefight system, air-condition and irrigation etc.
TRANSMITT ED MEDIUM
Type IZ pumps are used for pumping diluent, clean, un-corrosive water and liquids under 50℃ conglutination which characteristic of chemical and physical is similar to water in which does not contain solid granule or fibre.
WOR KING CON DITION
Temperature (Max.): 80℃
SCHEME
The electromotor adopts the type Y motor which with all-closed, fan refrigerant, close-couple and horizontal characters.
By provided 2 kinds of different installation structures, for structure I, the pump is put on the cast-iron motherboard. For structure II, the motor may be put directly on the horizontal base. It may be up to client's preference.
DESCRIPTION
Type IZ pumps use close-couple in structure which are driven by electromotor in case to reduce quantity of accessories. The suction and discharge flange, the casing and pump foot are all cast to a whole. With good function on absorbing water, high efficiency and resist on steam cauterization, the impellers with hydraulic and dynamic balance are adopted and cantilevering installed in the pumps. By used of excellent mechanical seal, the pumps are simple in structure, reliable in performance, small in size, light in weight, low noises, good resist on steam cauterization, low in power consumption and easy in maintenance.

OPERAT IONS
START-UP
●It should be clockwise when the pump goes round from the start side to the pump;
●Make sure the revolving of electromotor is proper and the pump is turned neatly before the pump is start up;
●Turn off the valve controlled for the pipeline;
●Pump is fill in water or lead in water to the vacuum pump;
●Connect the power supply, open the valve once the pump achieves to be turned properly then adjust to the condition you need. The pump could not work continuously over 3mins when the valve is turned off.
PAUSE
●Turn off the valve gradually and cut off the power supply;
●When the environment temperature is lower than 0℃, the water should be put out from the pump in order the pump casing will not be frozen to be cracked;
●If not in use for a long time, the pump should be disassembled, oiled and packed carefully.
WORKING
● When driving and operating, should pay attention to the reading of meters, to check if the bearing fever heated, shaft seal leaked & heated and the normal ofvibration and cacophony. Anything abnormal, it should take action at once.
● The maximum temperature of bearing can not high then 80℃, the surrounding temperature is not allowed to be over 40℃.
● The new cashing ring should be changed if there is damaged and worn part with the cashing ring and impeller.
WARNING
● Do not let the pump run dry, this could cause damages to the appliance;
● Check the bearing regularly;
● The pump should have its bracket. In order not to press the pump out, it’s not allow the weight of pipeline add to it;
● The absorbing pipe should be installed to each pump, and require as short as possible, few crooks;
● The bearing of weight is different as the pump is made by different materials. The working pressure should be accommodated with the bearing of the pump;
● When transition of the medium, please provide its characteristic of chemical and physical and verify with the supplier if the pump you chose is applicable in which including the pump casing and the material of shaft;
● The wiring and the circuit which between the pump unit and power supply should be maintained by the qualified professional.
