  Air Compressor Cut Off Switch Pressure Range: 15~60psi / 40~250psi / 400~500 psi Stable and accurate pressure switching Rare metal parts, durable quality Optimal for heavy duty commercial air compressors Robust structure for industrial harsh conditions   There are numerous types of lefoo pressure switch for air compressor cut off switch  that come on the market. In pressure switch manufacturer, Picking the right air compressor pressure switches depending on what the air compressing system is. A new pressure switch is usually more precise than repairing an old one, while adjustable digital pressure switches give you more convenience when using them.   Intelligent air compressor pressure switches made by LEFOO pressure control are instruments of pressure differential  measurement, display, and control. The air compressor cut-in and air compressor cut off switch can automatically control the relay output according to the pressure in the tubing. Compared with the ...

  300 GPD Pump / Pressure Booster Pump / Self-Priming Pump Work Flow: 2.6L/min or 2.7L/min Work Pressure: 0.5Mpa=70Psi Noise Level: ≦53db / ≦55db Max Current: ≦3.2A / ≦4.5A   LEFOO Offering Diaphragm Booster Pump, Water Booster Pump for reverse osmosis systems and water purifiers, and water pressure feeding applications since 1985.   300 GPD pump  can increase the pure water production rate for all Solid Filter Cartridges in Water Purifiers, Reduce the rejection water rate. Stable long term pressure adding of 70 psi, The ro water pump is quiet with workflow ≧2700ml/min ,  Ideal for water purifiers in kitchens, offices, and shops.   STILL NOT FIND THE DIAPHRAGM BOOSTER PUMP, HERE ARE SOME RECOMMENDATIONS: RO booster pump 100 GPD: This pump can remove 98-99 % of contaminants in the tap water or static water resource.      RO booster pump 150 GPD: This pump provide the power for the RO system which removes up to 99% of harmful pollutants such as...

  RO booster pump 100 GPD Pressure Booster Pump / Self-Priming Pump Work Flow: 0.98L/min or 1.05L/min Work Pressure: 0.5Mpa=70Psi Noise Level: ≦45db / ≦50db Max Current: ≦1.4A / ≦2.1A   The water purifier manufacturers can employ 100 gpd pump  as pressure boosting devices in their products. The reverse osmosis system can remove 98-99 % of contaminants in the tap water or static water resource. The ro booster pump 100 gpd can increase the water production efficiency by 70 psi pressure feeding.   REVERSE OSMOSIS OF RO BOOSTER PUMP 100 GPD Reverse Osmosis is the reverse process of natural osmosis. Solutions with low salinity and low density have a natural tendency to migrate to solutions with high salinity and high density. The reverse osmosis membrane of the RO water booster pump divides the water into two pass way, the permeated water passes through the RO membrane to the clean water tank, and the rejected water goes to the waste solution tank. The RO system will remo...

  Peristaltic pumps are very popular fluid transfer equipment with a wide range of applications. Peristaltic pumps can be classified according to the motor type into stepper motor peristaltic pump , DC motor peristaltic pump , servo motor peristaltic pump, explosion-proof motor peristaltic pump, etc.   The peristaltic pump with stepper motor , as the name suggests, is a peristaltic pump driven by a stepper motor. The stepper motor has good start-stop and reverse response, wide speed range and reliability, etc., and the lifespan can reach more than 100,000 hours. The small peristaltic pump  can meet the low pulse and accurate and reliable flow control required by precision instruments.   Let's LEFOO peristaltic pumps manufacturers take you to have a look:   There are also many types of stepper motor peristaltic pumps developed by LEFOO pressure control, which are often used in experimental fields.   The peristaltic pump using a stepper motor has the advantag...
