|
| BOWLS |
|
 |
The bowl assemblies are made of close-grained cast iron [with a small percentage of nickel to increase the density of metal]. They are hydraulically profiled to reduce friction to the water flowing upward and to convert high velocity into pressure head to peak efficiency and performance. The inner surface is coated with anti-corrosive paint. The bowls house the impellers and bronze bearing. Flanged joints connect two bowls with each other. |
| |
|
| IMPELLERS: |
|
 |
The vane angles of the impellers are carefully selected to achieve a higher manometric efficiency and the vanes are made extra-smooth to minimize hydraulic losses. The impellers are statically and dynamically balanced to the nearest working speed for a vibration less operation. This ensures a longer life. The impellers are machined accurately to match the contours of the bowls.
The running clearance of the impellers can be easily varied to change the capacity or to compensate for wear and differing well conditions while maintaining the same high capacity. Precision turbine pumps can give almost any combination of capacity and head by varying the type of impeller and the number of stages. The pumps can be fitted with closed impellers to draw clean; general-purpose water semi- open impellers can be supplied when sand, turbid water is to be drawn. Normally alloy cast iron impellers are supplied, but bronze impellers can be provided at marginal cost. The latter are indispensable when handling water containing mineral salts and sand or when hygienic water is required. Precision turbine pumps are almost universal in their application. They are engineered for normal use for pumping water from tube wells, deep wells, open wells, bore hole, lakes and rivers, They can be applied for general sump, condenser line and booster, transfer service, cooling tower, flood control and irrigation purposes, various wet and dry pit installations and for above floor level’ or ‘below ground’ suction and discharge. In fact precision turbine pumps can be installed to handle any quantity of water up to 25,00,000 liters per hour form depths up to 200 meters. |
| |
|
| Suction Case: |
| Made of cast iron, the strong suction case is hydraulically contoured to guide a uniform flow to the impeller. It is fitted with long bronze bearing [for the impeller shaft], a sand collar and a sealing plug for sand-free running and sturdiness. The conical strainer at the bottom prevents large foreign solid particles from entering into the suction case. |
| |
COLUMN ASSEMBLY |
| |
| COLUMN PIPES/RISING MAINS: |
| Water rises upwards between the casing pipes and these outermost heavy duty steel column pipes [API standard] which are made in standard lengths of 3 m. [10’] and or 1.5 m. [5’] with heavy duty external threads or with flanged joints. Column pipe couplings rigidly connect two column pipes. |
| |
| SHAFT ENCLOSING TUBES/CASINGS: |
| The shaft enclosing tubes, from which oil passes downwards to lubricate the line shaft, prevent the oil mixing with pumped water, protect the line shaft, and also hold the line shaft bearing in alignment. [Naturally the casing pipe is eliminated in water lubricated pumps]. Available in 1.5 m. [5’] standard length, they are coupled with bronze spiral-grooved, threaded bush bearings. Chemically treated rubber guide spiders provided at suitable intervals stabilize vibrations. The casing pipe being eliminated in water lubricated pumps, the cast iron stabilize [guide spider] containing cut-less rubber bearing is screwed or flanged to the column pipe. |
| |
|
| LINE SHAFT: |
|
 |
The solid line shaft, rotated from top by the prime mover, is made of high-carbon steel, threaded and ground. This strong line shaft is designed for 25% overload capacity at maximum power Consumption, and is coated with a special “ASFOSIL” plastic coating for rust protection and increased life. In water lubricated pumps the line shaft rotates, in rubber bearing, with the stainless steel sleeves, which have internal threads. The sleeves are locked by the line shaft steel coupling, which at the same time couples the two line shafts in oil lubricated pumps the line shaft rune through bronze bearing and the sleeves are eliminated. |
| |
|
| DISCHARGE CASE & TOP BOWL: |
| The body is made of close-grained cast iron. It is provided with outlet ports and long bearing, strong enough to guide the pump shaft for a vibration-free operation. The bearing is protected by a sand collar [bronze or plastic]. The stuffing box of the oil lubricated pump is provided with a bronze lantern ring and graphite asbestos gland packing to achieve perfect oil-water separation and to ensure a smooth oil lubrication system. |
| |
A SPECIAL FEATURE: |
| Imagine the cumbersome task of repairing a gland assembly, situated 100 meters below the ground, damaged by excessive water pressure. The discharge case of precision oil lubricated pumps features a special LABYRINTH bushing system [generally not found in other makes] which reduces the amount and pressure of water entering the stuffing box, thus preventing the direct action of water pressure on the gland packing. [The additional bronze bearing provided under the sand bushing also reduces the vibrations that would the disturb the packing]. |
| |
| COLUMN PIPES/RISING MAINS: |
| Water rises upwards between the casing pipes and these outermost heavy duty steel column pipes [API standard] which are made in standard lengths of 3 m. [10’] and or 1.5 m. [5’] with heavy duty external threads or with flanged joints. Column pipe couplings rigidly connect two column pipes. |
| |
|
| THE 4 WAY SEALING FEATURE OF PRECISION TURBINE PUMPS: |
 |
The bowl and impeller assembly of precision turbine pumps have a special 4-way sealing feature which ensures a perfect non-leaking fitting reducing the loss of liquid through bypass. The diagram shows how horizontal surfaces. This helps maintain the maximum performance and efficiency of the pump. |
| |
|
| WATER / OIL Lubrication |
 |
Whether you should select an oil or water lubricated system depends upon the type of water to be pumped, the type of installation and other factors. Major differences between the two types are in the column assembly bearing and in the discharge case. In a water lubricated pump, water is added before starting the pump to pre-lubricate the line shaft rubber bearings. The shaft enclosing tube [which separates the lubrication oil from discharge water in the oil lubrication pumps] is completely eliminated.
The extra shaft enclosing tube in oil lubricated pumps makes them sturdier, ensuring a smooth operation regardless of the frequency of starting and shutting of the pump. Such pumps are the ones most commonly used for irrigation and water supply schemes. |
| |
|
However, water lubricated pumps are indispensable when clear, cold, hygienic water free from oil and dirt is desired, Engineered to fulfill the complex design requirements and diversified needs of modern.
Industries, water supply and agriculture the precision oil lubricated/water lubricated turbine pumps save you time and money in performance and maintenance to give more water at lower cost per liter. |
| |
| Precision turbine pumps can draw from 15000 to as much as 25,00,000 liters [330 to 5,50,000 gallons] of water per hour from up to 90 m. [330’] depth, [specially designed pumps reach as deep as 200 m] from the tube wells with a minimum diameter from 100 mm. to 650 mm. [4” to 26”] They are manufactured in a wide range of sizes from 65 mm. x 50 mm. to 400 mm. x 400 mm. [2.1/2” x 2” to 16” x 16”]. |
| |
| DRIVING ARRANGEMENT: |
| Precision turbine pumps are adaptable to of prime mover and driving arrangement. If electric power is available, the pumps can be driven with a vertical hollow or solid shaft motors. They can also be driven by means of a petrol/diesel engine or even a tractor which drives the pump through a V or flat belt pulley hand with a hollow shaft. A right angle drive too can be provided for the pump with an oil engine through a horizontal flexible shaft. The safeguard against power failure particularly in a power house, the combination of an electric motor and pulley or right-angle gear head ensure an unfailing continuous supply of water. The pump assemblies’ can-be run at speeds between 1440 to 2,880.rpm. |
