Sundyne – Chemical Pump (Direct Drive)
Sundyne Direct Drive is a series of high-performance centrifugal chemical pumps with a direct drive, specifically designed for transferring aggressive, corrosive, and hazardous liquids in the chemical, petrochemical, pharmaceutical, and energy industries. The design complies with API 610 / ISO 13709 requirements and ensures maximum containment, safety, and process stability.
Basic models
LMV 311 / 317 / 318 — horizontal direct-drive pumps designed for high pressure and temperatures up to +400 °C.
LMC / LMW — vertical versions designed for chemical and process applications with continuous operation.
BMP / HMP — versions with an integrated gearbox and high-speed hydraulics designed for demanding reactive media.
Technical characteristics
Key series parameters: flow rate — up to 360 m³/h, head — up to 1400 m, power — up to 450 kW.
Materials: AISI 316 stainless steel, Hastelloy, Duplex, Inconel — for maximum corrosion resistance.
Pumped liquid temperature — up to +400 °C, pressure — up to 500 bar.
All models are compatible with explosion-proof execution (ATEX) and can be equipped with sealless magnetic drive options for complete containment.
Advantages
Absolute containment — minimizes the risk of leaks when handling toxic or volatile substances.
Chemical resistance — special alloys designed for aggressive acids, alkalis, and organic solvents.
High pressure and temperature — engineered for process applications with high energy loads.
Energy efficiency — a direct-drive system without couplings or belts reduces losses and vibrations.
Reliability in continuous operation — optimized hydraulics and rotor balancing ensure stable 24/7 performance.
Application
Sundyne Direct Drive are used in the production of acids, polymers, fertilizers, isocyanates, as well as in distillation, absorption, and rectification processes.
They are highly effective in chemical and petrochemical industries, in reactor feed systems, dosing, circulation, and the transfer of aggressive liquids under high pressure.
The company Steiner Ukraine supplies chemical pumps Sundyne Direct Drive from official manufacturing centers in the USA and Europe, providing engineering selection, commissioning, and service support in Ukraine.
