3. VERDERAIR e-PURE — Electrically driven double diaphragm pump (new generation)

e-PURE is an electrically driven double diaphragm pump based on an entirely new technology: a horizontal fluid flow path combined with flap valves instead of ball valves. This gives markedly lower friction losses, optimal fluid velocity, lower energy consumption and a longer service life than traditional diaphragm pumps.

Benefits

• Highly energy efficient
• Plug and play
• Less maintenance – longer service life

How does it work?

An electric motor drives a gearbox and shaft that create a reciprocating motion. The fluid moves horizontally through the pump (unlike traditional AODD/EODD pumps), and flap valves reduce the number of flow bends and moving parts, giving lower friction losses and lower energy costs.

Materials

The pump housing is made of solid machined PTFE or PE (UHMW). Other wetted parts (shaft, flap pin, diaphragm plates) are in PEEK and SS 316. Future material options: PEEK, duplex and Hastelloy.

Motor/drive

AC motor with 87 Hz technology and gearbox, giving a leak-free design with a small footprint. An optional frequency inverter on 220 V single phase gives adjustable flow rate and soft start.

Technical specifications

Key features / USP

Self-priming, can run dry, low pulsation, leak-free design, highly energy efficient, less maintenance/longer service life, plug & play, no need for expensive compressed air, low noise level, smaller footprint than traditional EODD pumps. With a frequency inverter (FI) the pump stops automatically if power consumption gets too high (e.g. a closed outlet).
