Sundyne – Multistage Chemical Pump (Integrally Geared)

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 series parameters: flow rate — up to 450 m³/h, head — up to 1600 m, power — up to 600 kW.
The design includes an integrated gearbox, enabling high rotational speeds while maintaining compact dimensions.
Materials — AISI 316 stainless steel, Duplex, Hastelloy, Inconel — ensure maximum chemical resistance.
All models comply with API 610 / ISO 13709 standards and can be supplied in ATEX explosion-proof versions.

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 pumps are used in the production of polymers, isocyanates, acids, monomers, in reactor feed systems, heat-exchange units, rectification installations, biofuel production, and high-temperature chemical processes.
They are the ideal solution for applications requiring high performance, containment, and long service life.
