ISO Back Pull-Out Centrifugal Pumps
CM - ISO end suction, back pull-out pumps are the result of our intensive R&D programs. All models are versatile and reliable multi-purpose pumps designed with many advanced features to achieve higher performances.
Designed to international ISO 2858 standard, the CM-ISO back pull-out pumps conform to strict dimensional specifications, ensuring sturdy and durable constructions. Common problems in hevy duty applications viz. shaft deflection, bearing failure and excessive wear are eliminated.
All pumps are tested to 24 bar pressure with working pressure up to 16 bar.
Optional item such as mechanical seals, wear rings, shaft sleeves and oil lubricated bearings can easily be fitted to meet different application requirements.
These pumps are ideal for pumping liquid in applications such as building services, mining processes, power generating systems, fire protection, civil engineering and general mechanical services.
Enclosed, hydraulically and statically balanced impeller, designed to give
maximum efficiencies and suction lift. Constructed with clearing vanes on the
back to reduce axial thrust, protect packing and shaft from wear by abrasive
High efficiency volute type with self-venting centre line discharge. Anti-swirl
vanes on the suction end to ensure stability of head. High strength casting to give
working pressure of up to 16 bar.
3. Back cover
The back cover provides the face contact between housing and casing making the
pump a rigid, integral structure. An innovative O-ring seal ensures a positive, leak-
4. Extra Deep Stuffing Box
Fitted with six packing rings, more than any other pumps. The split gland
facilitates easy packing replacement. Mechanical seals can also be easily fitted.
Two extra-large, heavy duty grease-packed bearings designed to give long,
trouble-free life. Both are well protected from external contamination.
Sturdy, oversized stainless steel shaft minimises deflection and provides longer,
Rigidly cast single piece housing gives maximum strength and longer service life.
