Product Description:

This series pump is of an horizontal and split type, with both pump casing and cover split at the central line of the shaft,both water inlet and outlet and the pump casing cast integrally,
a wearable ring set in between the handwheel and the pump casing, the impeller axially fixed upon an elastic baffle ring and the mechanical seal directly mounted on the shaft, without
a muff, greatly lowering the work of repair. The shaft is made of stainless steel or the 40Cr-plated, the packing sealing structure is set with a muff to prevent the shaft from worn-out,
the bearings are an opened-ball bearing and a round-post roller bearing and axially fixed upon a baffle ring, there is no thread and nut on the shaft of single-stage double-suction pump so
the moving direction of the pump can be changed at will without need to replace it and the impeller is made of copper.
Pump outlet diameter: 80~250mm
Capacity: 345L/s
Pressure: 3MPa
Temperature: normal temperature:normal temperature
Medium: pure water and similar to that of pure water

Q:What's the submersible pump?
Submersible pump is a pump directly on the water inside the pump, eliminating the water inlet pipe, eliminating the trouble of ordinary water, is very convenient, just a pool, pool, bucket, water tank water level is shallow to be able to work, meet your requirements of pumping drainage. Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.
Q:How to install circulating water pump for cooling tower?
Water pump, cold water pump and hot water pump, the specific installation depends on the location of the cooling tower and the location of the heat exchanger, high cooling tower position, the need for hot water pump, heat exchanger position high.The cooling tower, cooling tower (Cooling tower), is using water as coolant, from a system to absorb heat emissions to the atmosphere, heat exchanged to produce steam, steam heat to volatile evaporation dissipation, convection and radiation heat transfer principle to disperse industrial waste heat or refrigeration and air conditioning to reduce evaporation cooling device therefore, in order to ensure the normal operation of the system, device as a barrel. The cooling tower can be divided into natural ventilation cooling tower and mechanical ventilation cooling tower according to its ventilation mode.
Q:How to introduce water pump?
A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.A pump is a machine that transports liquids or pumps liquids.

Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.1, displacement pump: the use of working chamber volume changes in the period to transport liquid.2: vane pump: the use of blades and liquid interaction to transport liquid.
Q:Should the no-load power of the pump be equal to the rated power?
Manufacturers in order to make money, the nameplate marked "1200W", in fact, the maximum power of the motor, only 750W.
Q:Pump flow 6M3/H is an hour, how many tons of water?
1.5KW pump if the head 90 meters, then the flow of 2 tons, more than the most
Q:Do you need a stop valve for the pump at home?
Must be connected, in the low-end water pipe, the valve is also called the bottom valve is to prevent the intrusion of water, at the same time, but also to ensure the pump again next time when starting the pump and piping in enough water to prevent idling.
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
Is zero freezing?
Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
Export pressure reduction generally 2 reasons: 1, blade wear, 2. mechanical seal leakageThe increase of electric current should be caused by severe wear of the friction pairs of mechanical seals, resulting in increased resistanceIt is suggested that mechanical seals and blades be changed.
Q:How should the water pump breaker be selected?
Tell you a way, then go to the election, mainly to see his rated current to choose.The most general calculation of a KW==2 current (380V3 phase) 11KW==22 current, and then enlarge 1.2 times, that is, the current of the circuit breaker is selected to 25-30A. If it is started directly, zoom in to 1.5 times. Yes, no problem!! In addition, the 37KW 64 current short circuit selector 80-100A is ok.. Similarly, 4KW following unification can be done using 10A15A
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The motor is sure of electricity, isn't it? Is there a low voltage or broken phase (three-phase motor), these cases will cause the motor does not turn, or low speed (easy to block), so should be measured with a universal meter. Maybe the boot capacitor is broken. Or smell the smell of burning. It might be a short circuit between the motor windings. (bearings should be hard to break). Look for repairs if you suggest. You may not be good. Oh, capacitor. You can measure good and bad with a universal watch. If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter.
