Dynamic Pumps & Projects (I) Pvt Ltd

Clients can avail from us a quality assured range of Basic Canned Motor Pump. It is basically a centrifugal pump, close coupled with a canned motor without using any dynamic shaft seal, couplings and ball bearings. The absence of all these parts makes it more durable and efficient. The pumped liquid acts as a cooling agent as well as lubricating agent for motor and the sleeve type bearings respectively, disregarding any need for external lubrication. Generally, a three phase squirrel cage induction motor is used for driving these pumps. The stator of motor is hermetically contained in a stator containment that consists of an external frame tube. This containment consists of out board & inboard end plates and an internal cylinder liner. A non magnetic liner encapsulates the rotor, which is welded on the shaft. We seal both ends of stator liner (stator can) and rotor liner (rotor can), so that any part of the motor is not exposed to external environment or internal pumped liquid.

These pumps comprise a gas seal between motor and pump, which keeps the pumped liquid containing slurry from reaching the separation seal. A clean and compatible liquid is filled inside the motor chamber, where the bearings are located. We provide these pumps at highly cost-effective rates and in varying specifications as per the clients’ usage requirements. Our organization is also known for its efficient delivery system, which ensures timely conveyance of orders to the intended premises.

Our organization is a well-known manufacturer and supplier of High Temperature Insulation Type Canned Motor Pump. As the name suggest, these pumps are specially designed to handle high temperature fluids. An auxiliary impeller, located at the front end of rotor casing, is used to re-circulate the process fluids within the motor section and lubricate the bearings simultaneously. To maintain the fluid and motor winding temperatures under acceptable limit, we have provided an integrated heat exchanger and thermal isolation spacer as a part of these pumps. An adaptor separates the pump from motor thereby, preventing the heat transfer from the pump to motor.

Clients can avail from us a quality assured range of Vertical In Line Canned Motor Pumps. These are a favorite of our clients for transportation of all liquids containing gas or vapors. The heat generated during motor operation often causes liquid inside the pump to vaporize. These vapors occupy a lot of space inside the pump, causing quick deterioration of pump and motor. These vertical motor pumps prevent this by ensuring proper gas venting at the top of pump. Owing to their revolutionary design, the gas or vapor trapped inside the pump is constantly released outside even if the pump is stopped. The vertical construction also reduces radial load on bearings by transferring load to axial direction and then floating the entire rotor via hydraulic thrust balancing.

We make accessible for the clients, high performance Multistage centrifugal Pump. The accurate balancing of axial thrust over the entire range of flow by a balanced disk seat increases the efficiency of pump manifold. These pumps comprise a modular structure, easy to dismantle & assemble and are compact in size. Owing to their unique and simple design, all maintenance work can be accomplished on the field. These pumps offer the best performance in high head applications.

We are engaged in manufacturing and exporting of qualitative Regenerative Canned Motor Pumps. These are designed for highly volatile and difficult to seal fluid, where absolutely leak proof performance is required. Our well-equipped manufacturing unit uses advanced technology to develop a flawless range. Further, we are capable of providing customized pumps in exact compliance with the clients’ specifications.

We manufacture for our clients, highly efficient Reverse Circulation Type Canned Motor Pump. In these pumps the motors are equipped with reverse circulation line to ensure that the pumped liquid does not vaporize at any of the bearing in the pumps. The increase in vapor pressure of liquid, owing to heat input, while flowing between the stator & rotor, is compensated by an increment in pressure. The main characteristics on which, the operation of these pumps depends include vapor pressure, specific heat and viscosity of the liquid. Problems faced in pumping of gases like carbon dioxide, butane, ammonia, propane and ethane, which have steeper and higher vapor pressure curve & low specific heat, are resolved by reverse circulation line.

We specialize in offering Slurry Seal Type Canned Motor Pumps, which are mainly used for slurry applications. These are so designed, that the pumped liquid is prevented from entering into the motor chamber by a clean compatible liquid. This liquid enters in the pump from a rear inlet port through a back flushing line. This system also takes care of lubricating the bearings. In order to minimize the frictional and electrical heat, flushing fluid is circulated through an integral heat exchanger by an auxiliary impeller, which is located at the front end of the rotor. A clean and compatible buffer fluid supply is pumped in and constantly re-circulated within the motor section to provide cooling and bearing lubrication. This also prevents the migration of solids into the motor.

We make accessible for our clients a superior range of Steam Jacketed Canned Motor Pumps. These are fabricated using the best-in-class raw material and feature complete jacketing of the pump case, motor stator and the rear bearing. These pumps are known for accurate temperature control, while handling fluids with melting points lying between ambient and 140ºC. The outer body is also covered with a steam jacket, which prevents the liquid from solidifying during pumping operation.
