General Description

GS series split case pump are new type of single stage double suction centrifugal split pump with high efficiency and performance. It is widely used in delivering and transferring liquid, like municipal water supply system, waste water disposal, energy generating plant, mine and metallurgy industry, agriculture irrigation and flood disposal.

Performance range
Outlet diameter of pump  DN 80—800mm
Capacity       Q  22—116003/h
Head           H  7—200m
Temperature  T  -20℃~105℃
Solid grains  ≤80mg/l
Permitted working pressure ≤2.5Mpa

Instruction of pump type
GS300-700MA/4
GS: High efficiency Split case pump (single stage double suction centrifugal pump)
300: Outlet diameter is 300mm
700: The nominal diameter of impeller
M: remodel design of impeller
A: A\B\C separately represents that outer diameter impeller cutting

Structure
*GS pumps are horizontally installed, the casing and the cover of the pump are divided along the axis.
*The pump cover is above the shaft and the casing is under the shaft.
*The inlet and the outlet are under the shaft.
*The center-line of inlet and outlet is perpendicular to the axis.
*The rotor can be removed without disturbing the inlet pipe and the outlet pipe, only dismantling the pump cover while maintenance.
*The shaft seal uses packing seals or mechanical seals.

The direction of rotation
The rotation for GS series pump is clockwise looking from the motor to the pump, for example, the pump inlet is on the right, and the outlet is on the left. The motor can be connected with the other end of pump shaft according to customer’s requirements, meantime, the rotation, the direction of inlet and outlet are opposite to the above mentioned.

Material of main parts
The medium-contacting parts are made of cast iron.
The material of impeller: cast steel /brass /according to customer’s requirements.
Parts range
Pump, Motor, Coupling joint, Foundation plate and Mounting resistant cushion will be supplied when inlet diameter of pump is less than 200mm, more than 200mm inlet diameter will only supply pump, motor, coupling joint.
Remind:
Please indicate the material of main parts in your inquiry or purchase contract. Any special requirement, please don’t hesitate to contact us.

Q:Variable flow variable frequency water pump how to adjust the flow?
Flow plus transmitter control
Q:Why does the pump decay when connected in parallel?
Pump parallel mainly solves the problem of insufficient flow. After parallel, the flow is two and the sum of the pumps. When the flow rate increases, the pressure loss of the pipeline will increase, so the water pump flow in parallel will not be the sum of the two pump flow, but less than the sum of the flow rate. The solution is to increase the diameter of the water supply pipe, reduce the angle bend and shorten the distance.........
Q:What motor does the pump use?
Single-phase general use YL series, three-phase general use Y, Y2 series.
Q:Submersible pump reverse impact on the pump
Small amount of water, large current, long running time, easy overheating, or even burning pump.
Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
50HZ motors are usually not damaged if they run on a 60HZ circuit, but the speed will increaseConversely, the 60HZ device runs on the 50HZ circuit, and the speed drops.Because of their different frequency, make them synchronous speed rotating magnetic field winding is different, so the rotor induction (induction motor) speed will be different, the pump will naturally lift Gao Shaoxu, and often will not cause damage to the equipment, because many things are in the 50HZ 60HZ.Second, for synchronous motors, the increase and decrease of speed is much more obvious than that of induction motors, because their rotor and motor are synchronous and keep synchronous speed
Q:How to introduce water pump?
Using the results of 1, in the past, the general company will make a performance table, in which use the same type of pump operating conditions and you almost use down till now there have been no problem, what you can say.2, reliability. Power plants may care more about the reliability of the equipment than on the price of the pump. Of course, the technology and procurement of power plants are not stupid. They will weigh it themselves.3, pump efficiency. Because the general pump special large pump involves a power plant called "factory power consumption" index, the smaller the better the index, and your pump if it is efficient, it will reduce the target, the power plant may be interested.4, if you want to sell the pumps have their own technical characteristics, you can also be appropriate to describe it, but if you are a salesman, but the technology is not very proficient in it, and the best little power plant technical personnel, because they ask if you can not answer, its effect is counterproductive.
Q:Electrical design into!!! Is the water pump lamp waterproof?
No specific requirements are available
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:What is the difference between a fire pump and a living water pump?
Fire pump and life pump essential difference, simply said: in the materialBecause we are used every day in the life of the pump, so there is no rust phenomenon, and the fire pump can not occur even in a hundred years to spend time, even some of the fire pump until life exceed the standard is not used, only periodically, so in order to prevent emergencies caused economic losses and personnel to design special pump different from the life of pump material as fire pump. Single stage centrifugal pump. The multistage centrifugal pump and pump life principle without any distinction, but the material will cast steel replacing 304, 309 stainless steel or copper materials, different specifications of other fire pump structure, materials should use copper and stainless steel.
Q:How to change the frequency of a water pump with a pump?
Only trip is not to the frequency converter settings or phase sequence change, if not moved the settings and wiring, most of the reason is the original reversal, you also know that inverter turnover also has water.Check analog positive and negative polarity, inverter settings, and if there is no problem, change the phase sequence.
