OBI Centrifugal Pumps
Product Details
Our 250 series concentric Housings are of heavy duty construction to provide extended service life. The concentric design allows the distance between the impeller and the housing to be the same at
all points, allowing a streamlined flow even at cut-off.
The concentric housing not only eliminates turbulence and cavitation but also reduces the radial load on the bearings.
The 250 series open vane Impeller is designed to reduce turbulence, lower radial and thrust loads and provide a smooth flow of fluid through the pump. The impeller is designed to allow fluid
leaving the impeller to blend with re-circulating fluid to reduce abrasive wear of the casing.
The 250 series Shaft has a greater diameter to provide heavy duty performance with minimal shaft deflection. The shaft sleeve and mechanical seal can be replaced without removing the shaft from the
pump.
The outboard Bearing assembly comprises of two angular contact bearings with high thrust load ratings and a zero end play.
The inboard bearing is a heavy duty double row ball bearing with a high capacity to compensate for the larger impeller sizes and heavy duty applications.
The Stuffing Box is available for packing or mechanical seal operation.
Our 250 series Mechanical Seal is manufactured from the finest materials available today.
Our seal distributes drive torque over 10 drive tabs which are 25-50% thicker than others on the market, therefore reducing stress on the outer retainer.
All metal parts are manufactured using 316 stainless steel, elastomers are manufactured from viton and both rotating and stationary seal faces are tungsten carbide.
A full range of spare parts are available including seals, springs, nuts, bolts and studs
