Impeller pump EP Mini 3/4″+Bypass 400V 1.4t/h

Impeller pumps are self-priming pumps. They unite the characteristics of a rotary pump and a positive displacement pump into one.
The working principle is very simple. The rotating part of the pump is a flexible wheel (impeller), which is made of an elastomer material. This impeller turns in a casing, which has an eccentric form. Here the individual wings of the impeller are strongly bent, whereby the volume between the wings is decreased. On the suction side, the wings spread apart through residual stress. The suction area increases. A vacuum develops, whereby the pump independentaly self-primes.
On the pressure side, the wings are squeezed together. The gaps will become smaller and be emptied.

Impeller pumps exhibit a continuous pulsation-free pumping flow.
The pumping direction can be reversed without difficulty. Thereby, the impeller pumps efficiency does not change.
The impeller pumps are self-lubricating. Given that, without lubrication between the impeller and housing, frictional heat develops fast. The impeller pump may run unlubricated, but only briefly. The suction process must be completed within 30 seconds.

Advantages
• All pump parts are made of stainless steel,
• Gentle, almost pulsation-free transport
• Easy cleaning
• Quick removal
• Compact design, low weight
• Self-priming up to 3m wc
• Fluids with seeds, berries residues stems are transported without problems
