Stronger and longer-lasting with a double-structured diaphragm! 10 times the pressing pressure, 2 times the diaphragm lifespan (compared to our company). Introducing the W series diaphragm pump.
Air-Driven Diaphragm Pump "Backup Diaphragm Pump W Series" We would like to introduce a pump with a backup diaphragm from our large diaphragm pump NDP-40/50/80 series. 【Features】 ■ Strong discharge pressure! Thanks to the double structure of the PTFE diaphragm on the liquid side and the EPDM diaphragm on the air chamber side, it can handle discharge pressures of up to 20m (0.2MPa). ■ Long diaphragm lifespan! The diaphragm lifespan is approximately 2.5 times longer compared to conventional products (according to our comparison). ■ Diaphragm without a center hole The diaphragm on the liquid side does not have a center hole, eliminating the need for parts to secure the diaphragm on the liquid side. Cleaning is also easier. 【Conversion Kit】 For those who are already using our diaphragm pumps (NDP-40/50/80 series), we offer a "conversion kit" that allows you to convert your existing pump to the backup diaphragm specification. 【Trial Campaign】 We are currently running a campaign where you can try the diaphragm pump for free. (Until the end of September 2023) * Please check the link at the bottom of the page for campaign details.
