The Quantum series features a line of superior performance double suction horizontal split case centrifugal pumps, of robust design to meet today's demands in the industrial, municipal, agriculture and commercial applications. The range is designed with the tightest technical specification in mind, so as to achieve the highest level of efficiency and hyrdraulic performance for current and future process demands.
Incorporating advances in computer-aided technology, Quantum offers high efficiency performance, reliable & long life service resulting in energy-saving, less downtime & low maintenance cost.
The Quantum features a 'double-entry' impleller design which is optimised by Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA). It results in improved vane passage with excellent hydraulic characteristics; and exceptional efficiencies over a wide range of flowrates. The double-suction design minimises the axial thrust, hence prolonging the life of the bearings and the rotor assembly.
The impeller is statically and dynamically balanced in accordance to ISO1940.
Replaceable stainless steel shaft sheeves protect the shaft from wear and corrosion, and they extend through the entire length of the stuffing box.
Various configurations of shaft seal are available - mechanical seal types with a variety of material options; or packed gland configuration to specifically meet the application requirements. 'Unbalanced' mechanical seals in accordance to DIN24960 are installed for pumps operating in < 16bar pressure. For > 16bar operating pressure condition, 'balanced' seals are installed. Cartridge-type seals are available as option.
The sealing chambers/casing are designed to allow seals packings to be easily removed from the rotor assembly for repair & servicing without having to remove the upper casing.
Heavy-duty shaft to handle maximum loading. Shaft is short and rigid, ensuring minimum deflection and vibration-free operation, hence improve life of bearings and wear rings.
The shaft (and threads) has no contact with the pumped medium, hence ensuring a longer operating life and corrosion-free shaft.
Fitted with replaceable wear rings. They protect the pump casing from wear and allow simple maintenance of proper running clearances to reduce maintenance costs and maintain operating efficiency.
Sealed for 'life' grease-lubricated, radial ball bearings are installed as standard. For larger pump models, cylindrical roller bearings can be adopted. Oil lubrication is optional.
The upper casing is axially or horizontally split from the lower casing; and the suction & discharge flanges are in-lined and integrally cast onto the lower half of the casing. This design simplifies disassembly of pump by allowing upper half of casing to be easily removed for inspection, service and maintenance of the complete rotating hydraulic assembly without disturbance to the pipework and driver. The upper & lower casings, which are heavy duty designed for with standing high working pressure, are self-aligning, hence easing the mounting of the casings together.
The double volute design casing reduces radial forces on the impeller, and consequently the load on the bearings. In addition, the internal of the casings are epoxy-coated as standard to provide a smooth water passage.
Flanges can be drilled to ISO, DIN, BS or ANSI standards.
