Product Description:

ISL series vertical multistage centrifugal pumps are newly developed products to cater for the water supply and discharge in high-rise constructions to the standard of National Fire Bureau GB6245-98.Because of the use of the advanced energy-saving hydraulic model to feature high efficiency and wide performance range; they may better meet the operation requirements of users. Besides, they are structured vertical or segmental to feature safe and stable operation, long service life, small occupation space and easy installation and maintenance.

Working Conditions:
1、 Used to deliver clean water of noncorrosive medium similar to clean water in physical and chemical properties, with the volume of solid insoluble not exceeding 0.1% of unit volume. To deliver medium containing small particles, please specify when placing an order.
2、 Temperature of medium:-15℃~+120℃
3、 Maximum system working pressure not exceeding 2.5MPa.
4、 Ambient temperature shall be lower than 40℃, and relative humidity lower than 95%


This type of pumps is especially suitable for water supply and discharge in high and low rise residence constructions, hospitals, hotels, department stores, office buildings, water service in fire control, long distance and production process etc.

Q:Installation position of check valve for water pump
Check valves must be installed at the pump's exit and position before the outlet control valve for servicing the check valve.Jiang Yuanyuan 1985's statement has a problem:1. On the flow of water, because the fluid is continuous and incompressible, the water in any part of the pipe will not flow as long as it is cut off in any position in the pipe.2, self suction exhaust is formed within the pump in outlet pipe, check valve installed in the inlet, because the pressure is low, is not conducive to automatically open the check valve, and its resistance, easy to form a vacuum pump and cavitation.
Q:What is the current of the pump when it is started?
When the motor starts, the rotor changes from a prohibited state to a rotating state, requiring a great torque, and the current must increase. When the pump starts, because there is water, it is started with load, and the current will be greater.
Q:What is the difference between self-priming and non self suction?
Self suction pump, pumping water conservancy machinery used, composed of a pump body, a rotating assembly, leading assembly, trash cover, and inlet and outlet pipe, a blocking net general assembly; start the motor, dynamic linkage, rotary assembly in promoting the impeller centrifuge, bubble up surging, generates suction. The air inlet pipe, the outlet pipe from the pump body, air exhaust, water outlet pipe outflow, the water pump, excellent performance, deep suction lift, large flow operation, saving time and labor, is the most excellent mechanical pumps in the realistic society.1. self suction pump, as the name implies, pumping tube is under the condition of air, use form a negative pressure pump at work (vacuum), under the influence of the atmospheric pressure will be lower than the water pumping port, then discharged from the pump discharge end. Before this process, there is no need to add "diversion water". The pump with this capability is called a self suction pump".2., some centrifugal or rotary vane pump, before absorbing water, you must add "water diversion" in the pump cavity to form a closed environment, and then pump operation to form negative pressure, to achieve the purpose of water absorption. For example, a manual pump used in rural areas. No self-priming capacity of the pump, each time before adding water to add "water diversion", it is very troublesome.
Q:Is there a water pump with its own flow regulating function?
Pump with adjustable flow depends on your useThe ordinary displacement pump, which has a small flow rate, can set the flow rate per second into the system and is widely used in the laboratory.Large flow regulating flow pump is mainly variable frequency pump, through the electrical signal feedback regulation, change the pump water storage flow.The main thing is to see your flow, and then determine what you want to pump!
Q:What is the function of the backflow pipe of the fire pump?
Generally, it is used to test the fire pump.The procedure is to start the fire pump - turn on the return pipe - return the water to the pool.The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.For every hour of the 2m flow fand self-priming pump, a spray gun flow is obviously too small, forced to use the pump load, affect the service life of the water pump.Add a return pipe, split water pressure, the problem is solved, adjust the flow of the return pipe, you can adjust the size of the spray gun pressure.If the spraying, the return pipe also plays a full stirring role.
Q:Why can't sprinkler system and hydrant system share water pump in fire fighting system?
Code for design of sprinkler systems, GB, 50084 - 2001 (2005 Edition)The water pump 10. 2.1 systems should be set up independently, and should be a preparation or a preparation will set the standby pump ratio.10., 2.2, according to the two load power supply construction, it is appropriate to use diesel pump as a standby pump.Some of them used to be common pumps, and now the code emphasizes independence.
Q:Fire hydrant and fire pump adapter difference
Fire hydrant is out of water, the water pump is water supply to the pipe network
Q:Do you need a stop valve for the pump at home?
Pump used at home do not take the water stop valve, the water level is too low, it can not pump up. In addition, there is no stop valve, not immediately pumping water, will have to wait a short time.The valve is actually a floating ball valve, when water is accumulated to a certain height, the float top, open the valve linkage; row water, reduce the water level, the valve is automatically closed, it realizes automatic drainage to steam pipeline.
Q:What are the quota items for the complete pump installation?
Pump installation / anchor bolt installation anchor bolt hole, fill oar vibration cushion installation
Q:What is a 1 inch water pump?
A pump with a diameter of 1 inches.
