EBARA 3(L)(4) Series EN 733 Stainless Steel Centrifugal Pump
The EBARA 3(L)(4) series is a range of EN 733 standardised centrifugal pumps made of AISI 304 stainless steel (3 series) or AISI 316 stainless steel (3L series), with 2 or 4 pole motors. The volute is made by hydroforming, giving a sturdy construction and high efficiency.
The back pull-out design allows the impeller-motor unit to be removed without disconnecting the pump body from the piping. The 3LM and 3LS versions are also available in the Z version, with the support foot mounted on the motor bracket and rotatable by 90°, for installation in tight spaces. The 3(L)S and 3(L)P versions can be supplied with ATEX certified hydraulics and motor.
