BPO series single-stage double-suction open type centrifugal pump self-researched by the Company after absorbed advanced technology of similar products and combined application requirement of various customers. The series pump adopts excellent hydraulic model, wider type spectrum and better structure. Pump casing is produced by special machine tool, which ensures concentricity among shaft bearing, shaft and pump case, and provides better reliability and maintainability. Apply to municipal water supply and drainage, water circulation of air conditioner, agricultural hydraulic engineering, such as irrigation, drain flooded fields etc., industrial water supply system, firefighting system, water supply and drainage of

Proficiently designed, these pumps are the best available in the country. These are self venting type with back pull out design which affords quick repairs. These require minimum spare parts which save considerably on maintenance costs as well. With high degree of dimensional adaptability, ISO Serial Centrifugal Corrosion Resistant Chemical Process Pumps, undisputedly stand as an ultimate choice of every discerning buyer.

The Back Pullout Design with the help of a coupling spacer facilitates removal of the pump rotating element. After dismantling the casing cover, support foot, cooling water / heating connections and sealing liquid (if any) the complete pump rotating element can be withdrawn from the pump casing. The pipework remains undisturbed and the motor remains fixed to the baseplate. The pump rotating element can then be easily dismantled, repaired / overhauled and re-assembled without wastage of time for realignment of pump & motor.

Made from top quality material, these pumps dauntlessly are capable of with standing high friction with minimum wear and tear. Use of Stainless Steel – 316 as standard material of construction ensures effective resistance to highly corrosive liquids & slurries and has thus proved to be an ideal solution to most of hazardous pumping operations. Pumps for specific applications can also be made available in different combination of materials such as C.I., C.S., SS-304, SS-316 L, Bronze, Alloy – 20, Hastalloy B & C, titianium etc.

As standardised industry recognised centrifugal pumps,DIN24255/EN733 pumps can be installed or changed in place of other pumps.The added benefit is that the existing installation pipework does not need to be changed. This is because these DIN24255 and EN733 approved pumps are manufactured to a set of standardised dimensions.

Centrifugal pump is a combination of rotating parts (such as shaft, impeller, shaft sleeve, etc.) and stationary parts (such as pump shell, stuffing box, bearing box). Space or clearance needs to be left between the rotating part and the stationary part to avoid wear of mechanical parts. Through the clearance, the pressure fluid in the pump housing may leak to the surrounding atmospheric environment. Traditionally, gland ropes or packing are used to seal the gap. O-rings, gaskets / plates and airfoil seals are used to seal stationary parts, so these are called static seals. Labyrinth seals, lip seals and mechanical seals are used to seal the rotating shaft, so they are called dynamic seals. After World War II, the sealing rope was replaced by mechanical seal. Mechanical seals are also called face seals.

Mechanical seal is a key component in centrifugal pump. It prevents the leakage of pressure fluid by friction between moving ring and stationary ring with very smooth contact surface.

The above typical mechanical seal has five different sealing points (see Figure 2) to prevent the leakage of pressure fluid into the surrounding atmospheric environment.

The seal is located between the impeller, shaft and shaft sleeve, as shown in Figure 2, and the gasket is sealed. It prevents fluid from leaking through the gap between the shaft and the shaft sleeve (see Figure 3). It is the seal of the rotating impeller to the rotating shaft and shaft sleeve. There is no relative movement between parts during operation. The arrow in Figure 3 indicates the possible leakage path if the seal (gasket) fails.

The seal is located between the floating ring and the shaft sleeve, as shown in Figure 2, i.e. O-ring. It prevents fluid leakage through the gap between the floating ring (rotating part of the main seal) and the shaft sleeve, as shown in Figure 4. The seal rotates relative to the rotating part. During operation, the shaft sleeve and O-ring move relatively. The arrow in Figure 4 indicates the possible leakage path if the seal fails.

The rotating part and the stationary part are sealed by the rotation (mutual friction) of the floating ring relative to the stationary ring. Due to the spring force (the spring has a preload of 2 mm to 3 mm) and hydraulic load (the fluid pressure acting on the sealing surface), the floating ring and the stationary environmental protection remain in place. The seal rotates relative to the stationary part seal. The arrow in Figure 5 indicates the possible leakage path if the seal fails.

3) Adapt to the axial thermal expansion of the sealing ring. The heat generated by the contact between the sealing surfaces may lead to the thermal expansion of the sealing ring.

The seal is located between the stuffing box and the gland (gasket), which is a static seal. The arrow in Figure 6 indicates the possible leakage path if the sealing gasket fails

The seal is located between the stationary ring and the sealing gland, which is a static seal. The arrow in Figure 7 indicates the possible leakage path if the sealing gasket fails.
