Barmesa - SH4-U: 4" Self Priming trash pump flow

Barmesa SH4-U:4" Self Priming pump various speed flow curve

Barmesa SH4-U

4" Trash Pump, pedestal / frame mount. Self priming centrifugal solids handling pumps designed for Municipal and Industrial applications. Frame mounted pump, no base or motor. For economical, trouble-free operation in handling solids-laden liquids and slurries. Performance will vary with pump speed, see performance curves. Values given are for maximum at 1750RPM.

The combination of different sized pumps, impeller trims and speed variations ensure that the correct capacity pump will be matched to the exact requirements of your system, whether it's a small sub-division or a large waste collection system. These pumps feature a large volute design that allows them to reprime automatically in a completely open system without the need for suction or discharge check valves - and they can do it with the pump casing only partially filled with liquid and a completely dry suction line.
