Our Centrifugal Pump Range by " The Double Life
Corp" offers longer service, more power and easier maintenance than
conventional pumps on the market today. In addition they offer increased capacity and
head without increasing pipe or mounting dimensions.
Our 250 series pump has proved to provide greater savings on the toughest
jobs through extended life and enhanced performance.
Pumps can be sold as stand alone units or as complete packages.
Skid mounted units come
complete with engine/electric motor and shaft coupling.
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.
