This kind of pumps has the specialties as follows: 1)If there isn’t vapor to generate, You can turn off the adulterating-gas valve to increase the vacuum degree. 2) The improvement of the adulterating-gas valve can make the pump have adequate adulterating gas amount as pumping vapor, so the cogulable gas can be eliminated timely and the pump oil can be prevented from being lactic. 3) It is installed with the device that can make oil revival in which the oil,water and vapor can be frozen and separated, so the oil can be cleaned in time, and be used repeatedly,therefore, the working time of the pump is prolonged and the working reliability is increased.
This series of vacuum pumps can be used by themselves or as the backing pumps of the Roots pumps,diffusion pumps,molecule pumps and titanium pumps.With the adulterating-gas valve,the pumps can suck a little coagulable gas,humid air or the mixture of gas and vapor,but which can not contain particle-shaped solid matter.
W series of pumps adopt the circle-shaped stationary valve and its ultimate pressure (absolute pressure) is lower than 2600Pa,while the WY series of pumps adopt stripe-shaped moving valves,and it’s ultimate pressure is lower than 1300Pa? This series of pumps are principally used in the trade of chemical industry,medicine-manufacturing,light industry, architecture material and wiring etc..We also serve the no-oil pumps according to the demand of user.
WL series of standing reciprocating vacuum pumps are the renewed products based on the primeval W series of lying ones.Compared with the W series of ones, they have the specialty as follows: 1) The gas valves are installed on the cover and neck of the cylinder(the W series ones are on the body of the cylinders),so it can increase the area of cooling water.The process of compressing gas is approximately isothermal,so it can decrease the loss of power and can save energy by 10%~15%.The area it holds can decrease by 1/2. 2) The piston of the lying reciprocating vacuum pump will go down because of the weight of itself ,so it will be worn away unsymmetrically. The WL series of ones improved this shortcoming,it can decrease the wearing away of the moving units as piston and connecting pole; 3) We can serve the no-oil WL series of standing reciprocating pumps.
JZJ2S type Roots-water ring vacuum system consists of the major pump i.e. ZJ type Roots vacuum pump and the backing pump i.e. two stage water ring vacuum pump. It can pump not only the common gas but also the gas that contains vapor and a little dust. Compared with the common mechanical vacuum pump and water ring vacuum pump, it has some advantages as follows: it can endure the oil,vapor and tiny dust,its ultimate vacuum is high and its pumping speed in higher vacuum is great,so it is a kind of ideal vacuum-obtaining equipment for drying,dehydrating and gas-expelling in the trade of light-spinning,grocery and chemical industry etc..

In the application with solar panel, the function MPPT (Maximum Power Point Tracking) maximizes the input power for various conditions of radiation and temperature. When radiation grows, pump increases the rotation speed as well as the water flow . When radiation decreases (presence of clouds or different hours of the day), pumps reduces the speed and thus the water flow but still provide water until the radiation falls below the minimum value to ensure the operation. Installation Wilo-Actun OPTI HS pump can be installed with External control module or without it, so becoming a “plug and pump” system. If no external control module is used, signal cables can be used to control pump ON/OFF the connecting, for example, a float switch All the protections against overload, overvoltage and dry running are integrated into the on board inverter. If the signal cables are connected to the External control module, it is possible to: Control the electric parameters (current, power, voltage).
