Design advantages of Sundyne LMV and BMP integrally geared process pumps

Sundyne LMV and BMP integrally geared pumps are engineered to comply with API 610 OH6 specifications. The core engineering advantage is a compact single-stage hydraulic layout driven by a high-precision internal speed-increasing gearbox.

This design allows single-stage units to achieve high differential heads at low flow rates, replacing multi-stage machinery and cutting footprint.

Plants can configure LMV vertical in-line designs for pipe-mounted installation without structural baseplate foundation requirements, or select BMP horizontal base-mounted configurations.

High-strength stainless alloys, titanium and specialty metals protect wetted parts from erosion and chemical attack in refinery hydrocarbon, acid and high-temperature services.

Extreme head performance of Sundyne HMP pumps in fertilizer synthesis

Sundyne HMP multi-stage integrally geared pumps are built for extreme differential pressure services in continuous process units. These machines operate in synthetic fertilizer production, urea synthesis, purified terephthalic acid (PTA) processing and refinery hydrotreating loops.

The rigid design couples multiple stages with precision multi-speed gearing for round-the-clock service.

Models HMP 3000 and HMP 5000 deliver differential heads up to 4,420 meters with flows to 150 cubic meters per hour and suction pressure ratings up to 70 bar. The gearbox includes forced-oil lubrication with dual filtration and oil coolers.

At the first stage suction, an aerodynamic inducer lowers net positive suction head requirements to avoid cavitation.

ANSIMAG sealless magnetic drive technology for hazardous chemical transfer

Sundyne ANSIMAG sealless magnetic drive pumps provide total fluid containment for toxic, corrosive and aggressive fluids. Conforming to ASME B73.3 and ISO 2858 dimensions, the KF and KM series feature thick molded ETFE fluoropolymer linings.

The polymer barrier shields the ductile iron structural housing from corrosive acids, bases and halogenated solvents.

Because ANSIMAG pumps eliminate mechanical seals, they operate without external flush plans or barrier fluids. Drive torque transfers across a stationary non-metallic containment shell via permanent rare-earth magnets.

The composite shell prevents eddy current generation, eliminating heat transfer to the pumped liquid and minimizing energy losses.

HMD Kontro metallic magnetic drive pumps conforming to API 685 standards

Sundyne HMD Kontro GSP metallic sealless pumps are engineered to meet API 685 requirements for petroleum, natural gas and petrochemical applications.

Designed to handle flammable hydrocarbons, liquified petroleum gases and toxic process streams, their zero-emission construction eliminates fugitive emissions and mechanical seal failure modes in refinery processes.

For high-temperature thermal oil and heat transfer circuits, the HMD Kontro GT variant operates with liquid temperatures reaching 450 degrees Celsius without external cooling water.

The pump features silicon carbide internal journal bearings washed by the process fluid, along with instrumentation ports for secondary containment and temperature monitoring.

Sunflo industrial high-pressure pumps: reliable boiler feed and washdown

Sunflo single-stage industrial pumps (P-1500, P-2500 and P-3000) adapt Sundyne heavy-duty API gearbox heritage to general industrial fluid movement.

Sunflo units excel in boiler feedwater injection, reverse osmosis desalination, chemical water treatment and high-pressure cleaning in food processing, maritime transport and pulp and paper production.

The single-stage impeller and speed-increasing gearbox provide smooth, continuous flow without pressure pulsations typical of reciprocating plunger pumps. This pulsation-free delivery protects downstream spray nozzles, valves and piping manifolds from hydraulic shock.

A modular wet-end design allows rapid maintenance of seals without disturbing drive motors.

Component selection and maintenance practices for Sundyne rotating machinery

Reliable long-term operation of Sundyne rotating machinery depends on preventive maintenance intervals and factory-compliant replacement parts.

For LMV, BMP and process compressors, periodic monitoring focuses on aerodynamic inducers, open impellers, precision gear pairs, shaft bearings and cartridge mechanical seals to maintain hydraulic head and efficiency.

Comprehensive service kits include fluoroelastomer O-rings, spiral-wound gaskets, thrust bearings and precision fasteners for turnaround overhauls.

Component selection relies on the unique unit serial number stamped on the factory nameplate, ensuring full dimensional compatibility and alloy verification for the specific plant process conditions.
