High head low capacity pump, Available in S.S.-316 INVESTMENT CASTING and Cast Iron with all wetted parts of S.S.-316, Excellent for handling solvents from barrels and from tank farms to the charging vessels, Seal leakage can easily be detected from window in priming chamber, Pump can take negative lift from 3 to 5 meters, Life lubricating bearings, covered from both the ends so minor leakage from pump side does not affect bearings, Being a low speed (1450 RPM) pump, Less Maintenance is needed, Maintenance is easier, Drain arrangement is standard, Low overhang shaft arrangement giving minimum deflection at the seal faces, Installation is easier since motor required is vertical flange type and is directly coupled to the pump, coupling alignment is simpler, Biggest advantage from installation point of view is that since it is an "in line" type pump, it can be fitted as a valve and hence it will not require any suction or delivery piping efforts.

Ideal for sewage, industrial waste, liquids containing solid suspension, such as mash, pulps, beet shreds, etc. & muddy fluids of high consistency.   Vertical Dry pit Sewage pumps These pumps are most suitable for :- Drainage and irrigation installations Sewage disposal for housing colonies basement, toilet blocks etc. Marine installations   The basic advantages of these pumps are :-   Economy in floor space Prime mover can be mounted at an elevation as shown or at a higher elevation. Higher elevation of prime mover is possible by adding extra adaptors, transmission shaftings and intermediate bearings. This reduces the risk of submerging the electric motor in case of accidental flooding of the dry pit. Ease of maintenance. To dismantle, the mounting cover is to be unbolted from the casing after motor has been removed. The rotor assembly is drawn out upwards complete with stuffing box, bearing housing etc. This rotor assembly can then be completely dismantled at a convenient location. Due to the back pull out design, choking of the impeller can also be similarly, removed easily.   Automatic   Self priming sewage pump is a highly precise and yet a very rugged unit.The operation of the pump is as follows:A. vacuum pump starts.B. Water level in float chamber rises. Float rises and operates the level switch.C. Vacuum pump shuts down and main pump starts. Whilst main pump is in operation and pump looses prime then the priming pump restarts to automatically maintain the prime. As soon as priming is completed, the vacuum pump shuts down and main pump goes on operating. In case the level of product in the suction tank goes below the level of the suction line and pump looses its prime, the vacuum pump cuts in. The main pump continues to function for a predetermined time limit-approximately 2.5 minutes. After the predetermined time limit is over, the electric control panel shuts down the main pump motor. The whole system is absolutely automatic and has been developed after long research, to give outstanding performance under arduous service conditions.   Multistage Centrifugal pumps For high heads at relatively low speedsFor fire fighting servicesHigh rise building Boiler feedWater worksBooster serviceMine drainage Design Features Rugged and simple in design Maximum dimensional interchangeability Wide choice of materials Dynamically balanced impellers Vibration free performance The distinguishing features of these pumps are High Efficiency, Long Bearing Life and Adaptability to various operating conditions.The pumps are built as multistage pumps upto 10 stages with horizontal suction and vertical delivery branches. The intermediate stages are designed to lead water from the outlet of one impeller to the inlet of the adjacent impeller with minimum of friction, resulting in high efficiency. Special Designs Twin Outlet and Triple outlet multistage pumps are also available. The intermediate delivery housings are of special design and can be arranged after any number of stages depending on the head required at the intermediate delivery outlet. Hence a single multi stage multi outlet pump can perform the function of two or even three separate standard multistage pumps. These pumps can also be made self priming by the addition of a primary stage.

The Fluorinated Polymer are widely appreciated for their remarkable chemical inertness and their excellent resistance to ageing.POLYVINYLIDENE FLUORIDE (PVDF) offers the specific advantage of easy processing in accordance with all the convection methods used in the plastic industry. PVDF, polymerized, according to its own special process, offers a high degree of crystallinity to that by other processes, resulting among other things, in superior thermomechanical properties. The intrinsic technical superiority is one of the reasons for the success which PVDF has achieved on the world market for more than 20 years.

For measuring corrosive fluid line pressure with accurate readings from 0 to 10 kg/cm2   This engineered, all plastic Pressure Gauge Saver consists of a moulded cylinder incorporating a top and bottom chamber. It is an effective means of eliminating the corrosion problem and the necessity for utilizing a costly high alloy gauge in the measuring of line pressure in pipes carrying corrosive chemicals.   WORKING   A moulded flexible diaphragm incorporating double "O" rings separates the top and bottom chambers and provides for positive sealing as well as complete isolation of the corrosive fluids to the inert  materials.   The top chamber is filled through a 1/4" BSP threaded hole, with any compatible fluid such as water or oil. This liquid simply serves to the hydraulically transfer line pressure.  A pressure gauge indicator, of the user's choice, is then threaded onto the 1/4" BSP Connection.   In the lower chamber a 1/2" BSP thread ( or other pipe size) inlet is provided and when connected to the pressure line, provides the required channel for the fluid to enter and activate the flexible diaphragm, and a true and accurate reading ( to 10 kg/cm2) will be recorded on the pressure gauge.   This action also has the effect of dampening line pulsations, surges and shocks which are normally imparted to an indicator not protected with a Guage Saver.   The moulded flexible diaphragm is Neoprene. Polypropylene is rated for  kg/cm2  service. Polypropylene is suitable upto 85º C.

In Electroplating, it is necessary that certain corrosive chemicals in the electroplating bath are required to be continuously agitated or operated at high current densities. In such cases, solid particles remain suspended rather than settle at the bottom. These suspended particles cause roughness in plating.   In order to remove these suspended particles, continuous filtration of the bath is necessary which is done by Plate Filtration Unit. Plate Filtration Units are engineered to provide absolute and economical removal of suspended solid or organic impurities from the corrosive chemicals.   Filtration units are provided with resuable PP filter Cloth along with Filter Paper. Filter Units are also available with PP Filter Cartridges.   MODELS AVAILABLE : PFU 200, PFU 300, CFU 300 DUPLEX

Self-priming from a dry start. Pressures up to 100 PSI (7 bar). No close fit, sliding or rotating parts. Low internal velocity reduces wear. Quick assembly/disassembly with split clamp bands. Capable of pumping at high temperatures. Quiet, steady discharge flow without use of pulsation dampener. Safe for use in explosive environments. No electrical hazards or costly motor and control equipment needed. No pressure relief or bypass piping required because pump pressure never exceeds air inlet pressure. Pollution-free operation. The pump even improves air environment in confined areas. Air Operated Double Diaphragm Pumps   The air valve directs pressurized air to the back side of diaphragm 1.  The compressed air is applied directly to the liquid column separately by elastometric diaphragms.   The diaphragm acts as a separation membrane between the compressed air and the liquid.   Driving the diaphragm with air instead of the shaft balances the load and removes mechanical stress from the diaphragm, dramatically extending diaphragm life.   The compressed air moves the diaphragm away from the center block of the pump.The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm.   Diaphragm 2 is now on its air exhaust stroke; air behind the diaphragm has been forced out to atmosphere through the exhaust port of the pump.   The movement of diaphragm 2 toward the center block of the pump creates a vacuum within chamber 2.   Atmospheric pressure forces fluid into the inlet manifold forcing the inlet valve ball off its seat.   Liquid is free to move past the inlet valve ball and fill the liquid chamber. Why these Pumps Work Best The heart of the Double Acting Air Operated Diaphragm Pump is the air valve which shifts the air supply to both diaphragms alternately with complete reliability under all conditions of head and flow. The air valve performs this function with a simplicity in design and serviceability.   Top Performance in the most rugged pumping jobsPumps give dependable, top performance in the most rugged pumping jobs. Up to 50% solids and over 30 m. are no problem for the Pump.Material of construction Polypropylene Cast Iron Cast Aluminium S.
