Brief introduction of recirculating water vacuum pump:
Zhengzhou Greatwall recirculating water vacuum pump Oil-Free, portable, chemical resistant, 2-head recirculating water
pump simplifies maintenance, no more frequent and costly water
change. All major parts are made of PTFE, these economical vacuum
pumps are perfect for tough lab applications.
- SHB-Ⅲ: shell, flume, ejector, tee junction, check valve and
gas-extraction nozzle adopt the PP material; pump body and
impeller(six flow passages, dual seal) adopt stainless steel plate
pressing, the material is in accordance with the ANSI standard.
- SHB-ⅢA: ejector and gas-extraction nozzle adopt stainless steel material
(ANSI standard), the rest is the same as SHB-Ⅲ.
- SHB-ⅢS: pump body adopts the PP material, which is more suitable for acid
gas, the rest is the same as SHB-Ⅲ.
- SHB-ⅢG: spray paint Teflon(PTFE) on the ejector and gas-extraction nozzle,
gas pipeline adopts fluorine rubber material.
