Description
The HM-1110 Horizontal Metallic Monoblock Pump is a single-stage, end-suction, non-self-priming centrifugal pump in a compact, close-coupled construction. It is designed with an open or semi-open impeller and mechanical seal, driven directly by an electric motor to provide reliable transfer of thin, clean, non-explosive, non-aggressive liquids free from solid particles, fibres, and abrasive contaminants.
Its monoblock design integrates the hydraulic end with the motor, reducing coupling alignment requirements, minimizing installation footprint, and improving mechanical rigidity for continuous utility and circulation service. The HM-1110 is suitable for civil, industrial, commercial, and process-support applications, including wastewater and effluent treatment support systems, drainage and water extraction, HVAC heating and cooling circuits, air-conditioning and domestic water supply, irrigation networks, swimming pool circulation, electroplating utilities, shipbuilding services, firefighting booster duties, and food, beverage, and perfumery liquid transfer, where clean-liquid compatibility is maintained.
Technical Key Features
· Mechanical seal shaft sealing supports controlled leakage performance for clean-liquid operation.
· Compact horizontal configuration enables easy base mounting, piping access, and maintenance visibility.
· Close-coupled monoblock construction minimizes shaft alignment requirements and reduces installation space.
· Continuous-duty motor compatibility suitable for water supply, circulation, and process-support applications.
· Single-stage centrifugal hydraulic design suitable for clean water transfer, circulation, and moderate-head utility duties.
· Metallic wetted construction provides mechanical strength for industrial, civil, and commercial plant environments.
· Application versatility across HVAC, irrigation, firefighting, ETP/WTP support systems, swimming pools, and general industrial utilities.

Engineering Verification Note
The operating envelope above is inferred from comparable close-coupled, single-stage centrifugal pump reference data, including clean-liquid applications, single-stage volute casing design, operating pressure up to 16 bar (232 psi), and temperature capability from -30°C to +140°C (-22°F to +284°F). Final HM-1110 limits should be verified against the actual pump curve, motor nameplate, seal selection, and liquid compatibility before quotation or installation.
