Centrifugal Monoblock Pump isavailable from 2.2 to 3.7 kW in single-phase and from 1.5 to 11 kW in three-phase power supply. First of all motors and pumps are close coupled in a convenient and compact design for quick installation in limited space. Furthermore theyare fitted with a maintenance-free, mechanical shaft seal and single piece pump-motor shaft. Therefore these pumps have axial suction port and radial discharge port.The relative humidity of the location where these pumps are installed should be same or less than 95%.

• Water supply systems and irrigation
• For heating, cooling, air-conditioning and circulation plants. For civil, industrial and fire fighting applications
• Used for suitable liquids which are thin, clean, non-explosive, non-aggressive, not containing solid particles or fibers
• As pressure boosting pump for central water systems withlow pressure (follow local specifications if increasing networkpressure)
• Features
• • Reliable and robust construction.
  • They provide reliable water supply.
  • These pumps have built-in motor protection, dry running protection.
  • Due to back pull-out design which simplifies inspection and maintenance.
  • Most noteworthy is that these pumps have compact design with almost low noise level.
  • Sincethey are easy and simple in installation.Sothese pumps are user-friendly in operation.
  • Especially relevant is that these pumps have been designed to operate in a non-aggressiveand non-explosive atmosphere.

These systems are supplied as complete, preassembled andfactory tested systems including a close-coupled pump, bladder type pressure tank, pressure switch, pressure gauge(or electronic switch), special connector and flexible pipe forsystems with pump over the tank.These systems can provide sufficient water pressure formodern domestic appliances to ensure sufficient watersupply. Thus these systems are widely used in domesticwater applications to stabilize the pressure in the system andavoid the pump cycling on and off every time a tap is openedsomewhere in the house.

LVI pumps are non-self priming, single-stage, vertical in-line, close- coupled type centrifugal pumps having radial suction and radial discharge port. Vertical in line pump is designed for non explosive liquids which are clean, and thin without any solid particles. A viscous liquid affects the pump performance in the following ways.

• The power consumption of the pump will increase with increase in viscosity. This will require a larger motor for the pump.
• Head, discharge & pump efficiency will reduce.

The volute casing of Vertical in line pump is designed to be robust in construction to take the undue stresses offered by the pipe work. They have a radial suction port and radial discharge port. Standard flanges are PN 16 as per EN 1092-2 and PN 25 as per DIN standard EN 1092-2. ANSI 125 and ANSI 250 as per ASME B16.1 are available on request. The volute casing of Vertical in line pump is provided with a priming & drain hole closed by plugs. The impellers are closed impellers with extra smooth surface finish and machined completely from outside to ensure high efficiency. The direction of rotation of impeller is clock wise when viewed from the motor driving end. They are dynamically balanced to grade 6.3 of ISO 1940. All impellers of Vertical in line pump can be trimmed to adopt them for the duty point requested by the customer.

• Water supply
• Industrial applications
• Fire protection systems
• Cooling & heating systems
• Pressure boosting systems

• These pumps are available with mechanical shaft seal only.
• The pump impellers are dynamically balanced to grade 6.3 of ISO 1940.
• Vertical in-line pumps offer largest floor space saving compared to End suction & Horizontal split case pumps.
• These pumps have the discharge range up to 600 m/hr and head range up to 150 metres. Motor ratings are up to 132 kW.
• These pumps are close coupled pumps with TEFC squirrel cage induction motors with main dimensions complying with IEC standards.
• These pumps are available with our standard range of motors complying with EFF2 motors. They can also be supplied with EFF1 motors on request
• The in-line construction offers easy pipe work. Pipe hangers sized for the weight of the pump, piping & fittings offers adequate supports for most installations.
• The inlet passages of the volute casing are of liberal size & have flow straightening vanes to provide excellent suction performance and extremely quiet operation.
• Standard flanges for suction and discharge ports will be PN 16 as per DIN standard EN 1092-2 and PN 25 as per DIN standard EN 1092-2. ANSI 125 and ANSI 250 as per ASME B16.1 are available on request.
