Centrifugal Pumps

Product Details:

PEW" End Suction Pumps are non- self-priming single-stage, centrifugal volute pumps with axial suction port, centrally placed radial discharge port and horizontal shaft. Volute chamber and impellers are designed to give the best possible hydraulic efficiency and good suction lift characteristics. Most modern and highly sophisticated machinery and technology are engaged in manufacturing these pumpsets, using quality raw materials, dynamically balanced impellers and rotors to ensure long life.

These pumpsets are powered by a totally enclosed, fan cooled, AC Induction, two pole motor suitable for continuous duty with main dimensions complying with IEC standards. Motor stator is made of low watt-loss, silicon steel laminations assembled under pressure and rigidly locked in the frame. The windings are of high-grade enamelled copper wire and are varnish impregnated. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the pumps.

FEATURES

• Single shaft for motor and pump ensures good mechanical strength.
• Dynamically balanced rotating parts such as impeller and rotor.
• Bronze impeller available on request.
• Graphite coated asbestos packing rope is used to increase bush life.

Product Details:

A centrifugal domestic water pump is a reliable and efficient solution for water supply and transfer in households and small-scale applications. These pumps use the centrifugal force generated by a rotating impeller to move water, making them ideal for delivering water from wells, tanks, or reservoirs to homes and gardens. Known for their simple design and ease of maintenance, centrifugal pumps are widely used for domestic purposes.

Product Details:

PEW" split case pumps come with horizontal pump shaft and volute casing, which can be dismantled in the horizontal plane along the drive shaft.

These pumps are available in single and double stage. The single stage pumps have inline (symmetric) design, whereas the double stage pumps have asymmetric design.

FEATURES

Following are the significant features observed in PEW Split case pumps:-

• The split case construction enables removal and dismantling of the internal pump parts e.g. bearings, wear rings, shaft seal and impeller without disturbing the motor & pipe work.
• The pumps are non self priming, horizontal split case with radial suction and discharge ports.
• Flanges for suction and discharge ports are PN 16 and PN 25 as per DIN standard EN 1092-2.
• These pumps are long coupled pumps with TEFC squirrel cage induction motors complying to IEC standards and foot mounting.
• Pumps are available with gland packing as well as mechanical seal.
  The volute casing is provided with a priming & a drain hole closed by plugs. Impeller is of closed type with single or double curved blades and a smooth surface finish to ensure high pump efficiency. The impellers are dynamically balanced to grade 6.3 of ISO 1940. The impeller is of two types:
• Single-suction impeller with liquid entry from one side. They are used in two-stage pumps only and are mounted laterally reversed in a back to back manner.
• Double-suction impeller with liquid entry from both sides. They are used in single stage pumps only.
  Wear rings positioned between impeller and volute casing, protect the latter against wear and are easily replaceable
• These pumps are available in bare type or can be supplied as a complete unit with Motor (Eff 1 or

  2), coupling, coupling guard and fabricated steel base frame.

• DOR – Clockwise as seen from pump shaft end.

APPLICATIONS

• Pressure boosting for high rise buildings, hotels, industry etc.
• Industrial washing & cleaning systems.
• Fire Fighting systems – Hydrant, Drencher and Sprinkler pumps.
• Cooling & Air Conditioning systems.
• Boiler feed and condensate transfer system.
• Irrigation systems for fields including sprinkler & drip irrigation.

Product Details:

A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller's vane tips.

Product Details:

PEW" Multistage Vertical Centrifugal Pumps (PW series) are non self priming with inline design for ease of installation in constricted spaces. The suction and delivery ports are of same size and in the same horizontal plane. The mechanical seal and bearings are lubricated by the pumped liquid. All components like impellers, diffuser and shaft are made of corrosion resistant stainless steel and designed to deliver the best possible hydraulic efficiency.

Excessive Axial thrust is balanced by assembling the pump stages with equal number of opposed impellers. Balancing of axial thrust allows the use of standard flange mounted motors without special bearings. Working pressure on mechanical seal reduces to half, due to opposed impellers. The shaft is well supported by bush bearings ensuring noiseless operation.

FEATURES

• Dynamically balanced rotating parts ensure vibration free and noise less operation
• Good quality raw materials & hydraulic design facilitate longer life with high efficiency.
• Bottom casing fitted with Tungsten carbide bushes
• The in-line port design and compact footprint of these pumps allows for a clean installation.
• All models feature a shaft seal that can be replaced easily without the need to disassemble the entire pump.
• Pumps are equipped with high efficiency closed impellers,
• Pumps can be used for clear, nonabrasive, nonflammable liquids compatible with pump component materials.
