CONSTRUCTION SPECIFICATIONS
1. The motor shaft extension is coupled to a standard motor and is made of 316SS, a Teflon sleeve is installed over the shaft, there is no solution contact between the shaft assembly and the chemicals or solution being pumped.
2. The seal is cooled by the solution in the pump which running and by the design of the pump housing the mechanical seal is always submerged in solution so crystals cannot be formed around the seal when the pump is turned off.
3. CG/CK series, with the unique seal assembly, is easy to disassemble and replace. The fixed seal socket can be made of high temperature-resistant plastic PPS and is capable of operating up to 130oC while dry running. The remained liquid inside the pump head runs through the Teflon hose and cools the seal while dry running.
4. The unique Teflon bellows design with various seals such as Ceramic, Carbon, SIC and Hastelloy-C Spring ensure excellent durability in corrosion resistance. Fixed-seal & rotational-seal are made of various materials, SIC, Carbon, Ceramic and can withstand various chemicals.
5. Self-priming series, designed with self-priming cover excellent self-priming performance up to 20 ft. (3" in/outlet models cannot do self-priming well.)
6. Symmetrical body structure eliminates leakage due to deforming caused by injection molding.
7. The pump connections are standard 11/2", 2" or 3" flange connections depending on model and size.

Q:What's the difference between a double suction pump and a single suction pump?
From the literal sense to understand, double suction pump is the impeller at both ends of the water inlet, and the single suction pump is from the impeller at one end of the water.Dual suction is mainly used in the process of large flow and low lift. When the pump flow is greater than or equal to 280m3/h, the caliber of 200mm or more, if the use of a single suction pump, then the speed requirements of about 1450rpm in order to achieve the suction requirements. However, if the double suction pump is used, the size and weight of the pump are reduced, and the speed can be increased, the volumetric efficiency is increased, and the reliability of the equipment is improved.Single suction pump, also known as end suction pump, single suction pump flow is relatively small. The same flow, single suction of small size, but the axial force, bearing a large burden. The cost of single suction pump is low, the price is reasonable, widely used, but in many ways it is not as good as double suction pump. If the inlet pressure is higher, the general choice of double suction wheel can be solved. Because the axial force balance of the impeller of the single suction pump is a big problem.
Q:Difference between primary hot water pump and two hot water pump
Primary pump variable flow VPF (variable primary)Flow) system is the new layout of central air-conditioning system, compared with the one or two pump system has more advantages in initial investment and operation cost. At present, some with a pump with variable flow system engineering in the operation of many problems,
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
Q:I have a mechanical well how to choose the size of the pump
Deep well pumps can be used. According to your parameters. 0. 75 or 1. The 1KW deep well pump is in line with your requirements. Elephant 0. 75KW head can reach 70 meters. The water output in an hour is about 3 tons.. I wonder how much you get out of the water every hour. If the amount of water is small, you can buy a larger power point. General domestic deep well pump 0. 75 or 1. The price of 1KW is between 500-700. In the case of ordinary brands. The price of imported goods is between 600-900. The products at this price are generally of good quality.. Of course they don't sell your shoddy premise.
Q:55KW how large is the water pump wiring?
Transmission within 100 meters, 70 square millimeter aluminum cable, or 50 square millimeter copper cable. If you exceed 100 meters, you'll have to add a number to the cable.
Q:Why can't vertical water pump use spring shock absorber?
Vertical pump power is small, the weight is limited, the pipeline vibration is limited, the general rubber shock absorber will be enough. It's no use. I'm sure you can't use the spring shock absorber.General construction, 7,5KW below is rubber shock absorber, above is spring shock absorber
Q:Why does the pump head decrease when the pump flow rate increases?
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q:What is a water pump for?
A pump is a machine that transports liquids or pumps liquids. Mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. 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.
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
