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 pipework s .  The pumps c omply with DIN24255 and EN733 standard.

Design F eatures
Horizontal volute casing pump, single-stage with bearing housing, in back pull-out design.
>  Pump f lange standard: DIN25 01 , ISO7005
>  B earings : Deep-groove ball bearings, lubri cat ed  by engine oil   (Grease as option)
>  Shaft seal: Mechanical seal to EN 12756 or gland packing  (Gland packing as option)
> Coupling: The motor drive n  the pump through the fle x ibly coupling d i rect ly .
> The suction and discha r ge 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:  - 1 0 ºC  ~ 10 4 ºC .   
When working temperature exceeds 80 ºC , shall clarify clearly and in advance .
