High Pressure Horizontal Multistage Centrifugal Pumps

Precision-Engineered for Reliable High-Head Applications Manufacturer, Supplier & Exporter – PRECISION SEALLESS PUMPS PVT. LTD

In industries where high discharge pressure and continuous duty performance are critical, High Precision Sealless Pumps Pvt. Ltd. offer unmatched efficiency, reliability, and durability. Designed for high head and clean fluid transfer applications, these pumps are ideal for demanding industrial, utility, and process applications.

What is a High Pressure Multistage Centrifugal Pump?

Multistage centrifugal pumps are designed with two or more impellers (stages) mounted on a common shaft. Each stage adds pressure to the fluid, making these pumps perfect for high head, low to medium flow applications. The horizontal configuration ensures easy installation, maintenance, and alignment in industrial settings.

Key Features of Our High-Pressure Multistage Pumps:

• High Discharge Pressure: Achieved through multiple impellers in series
• Robust Design: Built to handle continuous operation under extreme pressure
• Precision Balancing: Dynamically balanced rotor and impellers for smooth operation
• Low Vibration & Noise: Ensures longer service life and quieter performance
• Leak-proof Construction: Mechanical seal or gland packing options
• Easy Maintenance: Modular design allows convenient dismantling and servicing
• Flange Standards: As per ANSI / DIN / ISO

Pump Construction:

Design

The pump design is multistage construction with verticle split casing & intermediates, allowing for high head discharge. It is a horizontal pump with a stage tie attached with suction & discharge brackets through rods. The pump base is cast integral with suction and discharge brackets.

Impeller

Impeller has axial thrust balancing and is die-casting with a very smooth finish to provide the highest efficiency level. In addition, impellers can be made out of any material depending on the customer’s process requirement.

Bearing

Heavy-duty ball bearings that are capable of carrying thrust load in either direction are used in pump design. In addition, grease-lubricated bearings are used, which ensure a longer life for the pumps.

Stuffing Box

Un-cooled soft-packing are provided with a sealing connection on the suction side of the pump. For higher pumped media temperatures, a stuffing box can be provided with a cooling cover which facilitates external cooling.

Flanges

All the flanges are faced and drilled as per DIN standards.

Drive

The pump is designed to drive by an electric motor through flexible coupling. The direction of rotations is perceived as clockwise when viewed from the driver’s end. As a result, suction is nearer to coupling and discharge at the other end.
