Product Overview: This product is suitable for strong acid, cooling electroless nickel electroless copper, special plating solution, wastewater and other corrosive liquid media, transportation and related equipments. Such as: plating equipment, chemical equipment, pharmaceutical equipment, circuit board equipment. Product Features: 1. Self-priming self-cooling design, since the suction is particularly strong up to 20ft, without cooling circulation loop. And the design of the check valve (check valve), within the pump to prevent liquid reflux; 2. Pump flow components using GFRPP, FRPP, CPVC, PVDF fluorine plastic rigid materials, corrosion resistance, and can be resistant to various acids, alkalis ; mechanical seal using a special material Teflon (Teflon (PTFE) + elastic sealing design, with different materials, such as silicon carbide (SiC), carbon, ceramic, resistant to various acids, alkalis and granular liquid and withstand various chemical medicine; confidential ceramic ring made of high-temperature plastic seat just to withstand the high temperature reached during idling 170 ℃, mechanical seal spring using nickel-based alloys (Hastelloy) + C alloys resistant to acid, alkali resistant , corrosion resistance, heat; 4. Applicable temperature: below 80 ℃; Technical parameters: Diameter: 40 mm - 80 mm flow: 5.0 ~ 80 m3 / h) Head: 5 ~ 28 m speed: 2900 r / min Motor power: 0.75 kW ~ 7.5 kW
