CLOSE COUPLED HORIZONTAL PUMP –
The
Close Coupled Horizontal Pump is a compact, efficient, and highly
reliable centrifugal pump designed for a wide variety of industrial,
commercial, and municipal applications. Known for its simple design, easy
installation, and low maintenance requirements, this pump type is ideal for
transferring clean water and other non-corrosive liquids efficiently and
cost-effectively.
Overview
A
Close Coupled Horizontal Pump is a centrifugal pump in which the pump
and the motor are directly connected on the same shaft, forming a single,
compact unit. Unlike long-coupled pumps that use an intermediate coupling or
baseplate, this design eliminates the need for shaft alignment, making it
easier to install and maintain.
Because
of its horizontal configuration, the pump provides excellent stability, smooth
operation, and convenient accessibility for servicing. The close-coupled
construction also ensures maximum efficiency in power transmission, reduced
vibration, and space-saving installation.
These
pumps are widely used in water supply systems, pressure boosting units,irrigation, HVAC systems, process industries, and general water circulation.
Their durability, energy efficiency, and cost-effectiveness make them one of
the most popular choices across multiple industries.
Design and Construction
The
Close Coupled Horizontal Pump is designed to provide high efficiency and
consistent performance with a minimal footprint. The pump’s casing, impeller,
and other hydraulic components are precision-engineered to ensure smooth flow
and reduced energy loss.
Key design elements include:
- Pump Casing: The pump casing is
typically made from cast iron, ductile iron, or stainless steel, depending
on the liquid handled. The casing design provides a volute shape for
efficient conversion of velocity into pressure energy and reduces
hydraulic losses.
- Impeller: Dynamically balanced,
closed or semi-open impellers are made from bronze, stainless steel, or
engineering-grade plastics. The impeller design ensures high efficiency
and minimal vibration.
- Shaft: The pump shaft, made from
stainless steel (SS 304 or SS 316), is corrosion-resistant and provides
superior strength for continuous operation.
- Mechanical Seal: A high-quality mechanical
seal or gland packing prevents leakage, ensuring safe and reliable
operation.
- Motor: The motor is a standard
TEFC (Totally Enclosed Fan Cooled) or IP55-rated electric motor suitable
for continuous operation. The motor and pump are perfectly aligned at the
factory, eliminating the need for field alignment.
The
horizontal design provides stable mounting, easy accessibility for maintenance,
and better serviceability. It also allows for installation on a flat surface,
eliminating the need for a heavy foundation or base frame.
Working Principle
The
Close Coupled Horizontal Pump operates on the centrifugal forceprinciple. When the impeller rotates, fluid enters the eye of the impeller
and is accelerated outward through the impeller vanes. The velocity energy is
then converted into pressure energy as the fluid passes through the volute
casing and exits the discharge outlet.
Since
the pump and motor are directly connected, mechanical losses are minimized,
ensuring high overall efficiency. The design also minimizes vibration,
alignment issues, and noise, resulting in a smooth and quiet operation.
