Using reliable quality motor,380V or 220V or direct current machine is optional.

Features

1.Very high safety of operation. Mechanical actuate diaphragm. Changeable eccentric drive

2.Power off seal,no leakage,with security delivery device,simple maintance

3.It can transport high-viscosity mediums, corrosive liquid and dangerous chemical goods.

4.The flow can be controlled via adjusting the length of stroke or the motor frequency.

5.The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.

Purpose

Widely used in petroleum, chemical industry, electric power, metallurgy, mining, shipbuilding,light industry, agriculture, national defense department and etc.

Q: Piston filling and peristaltic pump filling which precision is high?: These two pumps are used as a metering pump to use, so the accuracy is to be on a par with the peristaltic pump has more advantages than the piston pump is the largest energy fluid conveying there are particles, and the piston pump is smaller than the peristaltic pump pulse, so we need to choose according to the material characteristics you need to transport.

Q: What are the general water pump failure, how to repair?: Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.

Q: What should I pay attention to when buying a pump?: Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.

Q: How to select metering pump head?: The manufacturers of chemicals will give relevant recommendations, or consult the ProMinent chemical corrosion chart to determine the compatibility of the chemicals with the contact material.

Q: Pump unloading in hydraulic transmission,: Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving

Q: Concrete pump 125 pipe wall thickness: Concrete pump, also called concrete pump, consists of pump body and pipe. The utility model relates to a machine for continuously conveying concrete along a pipeline by utilizing pressure, which is mainly used for building, bridges and tunnels

Q: Why does the centrifugal pump start and close first when the outlet valve is closed?: The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact

Q: How can I buy a pump?: Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.

Q: What is an industrial water pump?: Industrial water pump, water pump for industrial production.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.

Q: Significance of water pump model ISO50-160: 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 parameters include flow, suction, lift, shaft power, water power, efficiency and so on;
