1、 Product introduction
Sk water ring vacuum pump is a single-stage, double acting, radial inlet and exhaust water ring vacuum pump; It is listed as energy-saving electromechanical products by the state. Sk type water ring vacuum pump is usually used to pump gases that do not contain solid particles, are insoluble or slightly soluble in water. Because the gas is nearly isothermal compressed during the working process of the water ring pump, it is also particularly suitable for the suction and pressure delivery of flammable and explosive gases. Pumps generally use water as working fluid.

2、 Product features
1. Single stage double action, radial inlet and exhaust, high efficiency and energy saving;
2. The structure is firm, durable, long service life, and can operate continuously for a long time;
3. No direct mechanical friction, no contact between impeller and pump body and no wear;
4. There is a proper gap between the impeller and the distributor, which is not sensitive to dust and particles;
5. It is convenient to disassemble and install the pump body and support feet horizontally;
6. Various specifications are equipped with corresponding atmospheric ejector to improve the suction vacuum.

3、 Technical parameters
Pumping rate: 9-146m³/ min
Suction vacuum: 80-1013hpa
Discharge pressure: 1013hpa
