Product Description Product Description eccentric mechanism drive, rugged, compact design, no dynamic seal, no leaks; flow rate adjustment for variable eccentric sliding axis (Z-shaped shaft) regulatory agencies; plunger rod drive. Performance and advantages rugged, compact design; no dynamic seal, no leakage, seal performance is better than piston. Variable eccentric mechanism to adjust, to ensure smooth flow pulsation changes. High accuracy, steady precision of up to 1%. Built up the oil valve guarantee limit amount of hydraulic fluid, built to ensure the safety valve diaphragm to avoid liquid shocks. When conveying corrosive slurry and explosive and other dangerous chemicals, can be double diaphragm with diaphragm rupture alarm device. Applications for environmental, petrochemical, chemical, electric power, metallurgy, medicine, food, etc., especially in high-precision, high-pressure, high-temperature field of outstanding performance. Technical Data Flow Range: 45L / h ~ 1100L / h maximum discharge pressure: 19MPa turndown ratio of 10: 1, the steady-state accuracy of 1% of the maximum suction lift height of up to 2m of water medium temperature: -10 ℃ ~ 100 ℃ up to + 40 ℃ environment ., the highest elevation of 1000m pump if there are other questions, you can contact us (http://www.cnpumpcn.com) will be happy to serve you, Mobile: 18925478337 Thank you!
