Description
The HC-1120 Horizontal Metallic Coupled Pump is a robust, single-stage, end-suction centrifugal pump designed for continuous industrial liquid transfer where mechanical stability, service accessibility, and long operating life are required. Its metallic wetted construction, rigid bearing housing, separate drive coupling, and field-serviceable seal chamber make it suitable for clean, mildly contaminated, corrosive, utility, and process liquids across demanding plant environments.
The pump is engineered for use in process plants, chemical handling systems, refineries, effluent treatment plants, seawater reverse osmosis support systems, condensate transfer, fire-fighting service, and general industrial duties. The coupled configuration allows motor and pump alignment flexibility, easier maintenance, and adaptation to different motor ratings, seal types, and metallurgy requirements based on the pumped fluid and site conditions.
Technical Key Features

· Available with gland packing as well as a mechanical shaft seal.
· Back pull-out serviceability for reduced downtime during maintenance.
· Rigid bearing housing design for stable shaft rotation and improved seal life.
· Horizontal coupled arrangement for independent pump and motor maintenance.
· Heavy-duty metallic construction for process, utility, and industrial liquid handling.
· Pumps and motors available with fabricated steel base frame according to EN 23661.
· Applicable across continuous and intermittent operation in process and utility systems.
· Field-serviceable seal chamber suitable for gland packing or mechanical seal configurations.
· Wide material flexibility for corrosive, abrasive, seawater, condensate, and wastewater duties.
· Motor, bearing bracket, and impeller can be removed for servicing without disturbing the volute casing or suction and delivery pipes.

Selection Note
Some technical values above are inferred from common horizontal metallic coupled process pump practice because detailed duty-point data were not provided. Final selection should be verified against flow rate, head, NPSH margin, fluid properties, casing rating, motor rating, seal arrangement, and site operating conditions.
