Sundyne HMP multi-stage pumps with an integrated gearbox

Sundyne Multi-Stage Integrally Geared Pumps (multi-stage high-pressure pump) is a series of high-head chemical pumps with a built-in gearbox, designed for pumping aggressive, toxic and explosive liquids in the chemical, petrochemical and power industries. Thanks to multi-stage hydraulics and a compact design, these pumps provide a high head with a stable flow and low energy consumption.

Basic models

• P300 / P340 / P400 Series — three-stage pumps designed for high-pressure applications, optimized for chemical processes, reactor feed systems, and recirculation loops.

• LMC / LMW High-Pressure — vertical multistage configurations designed for compact installation in production facilities with limited space.

• HMP / BMP — reinforced versions with temperature resistance up to +400 °C and operating pressure up to 500 bar.

Technical characteristics

Key parameters of the series: flow rate — up to 450 m³/h, head — up to 1600 m, power — up to 600 kW. The design includes an integral gearbox, which makes it possible to achieve a high rotation speed with compact dimensions. Materials — AISI 316 stainless steel, Duplex, Hastelloy, Inconel — ensure maximum chemical resistance. All models comply with the standards API 610 / ISO 13709 and can be supplied in an ATEX explosion-proof version.

Advantages

• High discharge pressure in a compact design — achieved through multistage hydraulics and an integrated gearbox.

• Absolute containment — available in a sealless version for toxic and volatile liquids.

• Chemical resistance — suitable for acids, alkalis, polymers, hydrocarbons, and aggressive solvents.

• High reliability — engineered for continuous 24/7 operation with minimal maintenance.

• Energy efficiency — the optimized gearbox and hydraulics reduce energy consumption while maintaining high performance.

Application

Sundyne Multi-Stage Integrally Geared are used in the production of polymers, isocyanates, acids and monomers, in reactor feed systems, heat exchange units, rectification plants, in biofuel production and in high-temperature chemical processes. This is the ideal solution for conditions where high capacity, leak-tightness and durability are required at the same time. The company Steiner Ukraine officially supplies Sundyne Multi-Stage Integrally Geared Pumps (multi-stage high-pressure pump) in Ukraine, providing technical selection, commissioning and service maintenance.
