Vertical Inline Pumps

Product Description

Vertical Inline Pumps;

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-explosiv 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 customers

Applications:

• Cooling & heating systems.

• Pressure boosting systems.

• Industrial applications.

• Water supply.

• Fire protection systems

Features:

• Vertical in-line pumps offer largest floor space saving compared to End suction & Horizontal split case pumps.

• 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.

• These pumps are close coupled pumps with TEFC squirrel cage induction motors with main dimensions complying with IEC standards.

• These pumps are available with mechanical shaft seal only.

• These pumps have the discharge range up to 600 m³/hr and head range up to 150 metres. Motor ratings are up to 132 kW.

• The pump impellers are dynamically balanced to grade 6.3 of ISO 1940.

• These pumps are available with our standard range of motors complying with EFF2 motors. They can also be   supplied with EFF1 motors on request

Reliable Performance for Demanding Applications

Designed with a closed impeller and single volute, these vertical inline pumps deliver exceptional hydraulic performance for water supply, HVAC, fire suppression, and industrial processes. The stainless steel shaft, heavy-duty ball bearings, and mechanical seal ensure durable, low-vibration operation even under challenging conditions.


Easy Installation and Maintenance

Featuring an inline, flanged mounting configuration compliant with both DIN and ANSI standards, these pumps are straightforward to install and service. Their vertical structure saves valuable floor space and the epoxy coated finish provides enhanced corrosion protection for extended operational life.


Safety and Efficiency Assured

Electric motor-driven operation with IP55 protection safeguards against dust and water ingress, ensuring reliable, energy-efficient performance. Low noise levels and robust construction make these pumps ideal for noise-sensitive or high-demand environments where consistent operation is critical.
