  A small peristaltic pump   has multiple rollers compressing a tube as they rotate around a partial circumference inside a pump body. Between the rollers, a chamber of liquid is trapped, and it is transferred from the inlet side to the outlet side of the small peristaltic pump.   Small Peristaltic Pump LFP401/ST  as a type of stepper motor peristaltic pump,  is a peristaltic pump driven by a stepper motor.   For the greatest accuracy and controllability, a small peristaltic pump is most often driven directly by a stepper motor. Such motors allow the user to precisely control the small peristaltic pump speed (typically between 0 and 500 rpm) and direction. These motors are generally a 2-phase bipolar construction and require a separate external driver to generate the correct sequencing signal to the motor coils. Bulk buy peristaltic pumps cheap direct from Lefoo peristaltic pumps manufacturers.   Features *Convenient start/stop, speed increase/decrease...

  Most Reverse Osmosis membranes have ideal minimum pressure such as 50 psi or 60 psi.  When the pressure is insufficient the RO system will generate less drinkable water at a low purify effect. The 150 gpd ro booster pump   will increase 75 psi pressure. The RO pump can be used in a water purifier of 150 gallons per day. The RO Booster Pump 150 gpd   can generate more high-purity freshwater with less rejected water. Commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase pressure when required. This ro booster pump 150 GPD is designed for both intermittent duty and continuous operation.   Features of RO Booster Pump 150 GPD *High water preventing level. *Compliant with CE, Rohs, CQC certifications. *Large flux water outlets with stable pressure and long working life. *Compact structure consists of robust plastic and metal components. *DC Powered strong impetus motor with low ...

  The RO booster Pump 100 gpd   is a pressure feeding device used in the  RO water system or water purifier 100GPD. The pump will add 70 PSI pressure to water which will enhance the pure water production efficiency. Its working flow is 980 psi, low noise, low current, and adjustable pressure setting. The ro booster pump 100 gpd is also used in Soda water Dispensers, Coffee vending machines, Water Dispensers, and, Misting Hydroponics /Aeroponics.   Features of RO Booster Pump 100 GPD *High water preventing level. *Compliant with CE, Rohs, CQC certifications. *Large flux water outlets with stable pressure and long working life. *Compact structure consists of robust plastic and metal components. *DC Powered strong impetus motor with low noise, low vibration level. *Whole process quality controls in processes of electrical, sealing, and pressure boosting.   Applications of RO Booster Pump 100 GPD Water Treatment/RO Carbonation Systems Beverage/Coffee Systems Water V...

  Pressure Range: -100~100kpa Pressure Accuracy: 1%FSO Work Temperature: 0~50 ° C Measure media: Non-corrosive dry gas Output: digital 4~20ma/1~5V, Swith NPN /PNP   LEFOO digital pressure controller   pressure measurement The piezo-resistive works on a Wheatstone bridge principle that will undergo deformation due to pressure on its area and change resistivities on 4 bridges, this is called the piezo-resistive effect. Usually, four strain gauges are embedded and connected to a Wheatstone bridge.  The signal amplifier amplifies the measuring signals from the strain gauge and Wheatstone bridge and synchronously optimizes the results, and the results are transferred by the squeezing electric power of the silicon wafer.   The digital air pressure switch   is used to replace electric contact pressure gauges and used in systems with higher requirements for industrial control. This digital LEFOO   pressure switch has a wide application in monitoring and contro...

  This brushless RO booster pumps   series is powered by a permanent magnet brushless motor, 0.5/0.7 Mpa pressure feeding,42~45db noise level, adjustable pressure, Workflow 2.7~5Liter per minute, Max current 3.2~5.0A   What is a Brushless RO booster pump? A brushless ro pump   employs the NdFeB permanent magnet arc motor that has no-brush, which provides tremendous magnetic torque and has the lowest noise level, Lefoo brushless pump pumping pressure for Reverse Osmosis water system which can generate 300-1000 gallons per day. Helps increase the pressure and volume of reverse osmosis water that flows to the storage tank, to the tap, to the faucet or showerhead. low tap water pressure under 40 psi is a nuisance in daily lives. Low water pressure can be fatal In food and beverage RO water applications, A brushless ro water pump   may be the ideal solution to offer the pressure for commercial RO water systems from Lefoo .   What is a Reverse Osmosis System Reve...
