General Description
EA End-suction single stage centrifugal pump is back-pull-out design, which allows disassembling the casing cover and rotary components without removing the pipeworks. The pumps comply with DIN24255 and EN733 standard.
Design Features
Horizontal volute casing pump, single-stage with bearing housing, in back pull-out design.
> Pump flange standard: DIN2501, ISO7005
> Bearings: Deep-groove ball bearings, lubricated by engine oil (Grease as option)
> Shaft seal: Mechanical seal to EN 12756 or gland packing (Gland packing as option)
> Coupling: The motor driven the pump through the flexibly coupling directly.
> The suction and discharge flange, the casing and pump foot are all cast to a whole.
> The pump casing, impeller and the pump cover are all made of cast iron or others, the shaft is made of high tensile steel, the sealing box is sealed by means of soft-packed or mechanical seal; the shaft sleeve is made of stainless steel, the support foot which is an auxiliary frame to the mounting frame is made of steel.
Operation Conditions
Fluid: Pure liquids not chemically or mechanically aggressive to the pump materials, Maximum solids content of the liquid pumped 40mg/L, 80mg/L with intermittent operation.
> Working Temperature Range: -10ºC ~ 104ºC.
When working temperature exceeds 80ºC,shall clarify clearly and in advance.
> Operating pressure:
PN1.0 MPa - Hydrostatic test pressure = PN1.6MPa
PN1.6 MPa - Hydrostatic test pressure = PN2.4MPa (optional)
Specifications
> Pump suction flange (mm): DN50 to DN300
> Pump discharge flange (mm): DN32 to DN250
> Capacity Q: Capacities to 1080 m3/h
> Head H: Heads to 155 m
> Liquid temperature: -10ºC up to +104ºC
> Speed: 50Hz - 1450rpm / 2900rpm, 60Hz -1750rpm / 3550rpm, 3600RPM Max.
> Wide hydraulic coverage
> Low NPSH requirement
The Direction of Rotation
The rotation of the pump rotor is clockwise looking from the motor to the pump.
