HMD Kontro Sealless Pumps

What HMD Kontro Sealless Pumps does

HMD Kontro Sealless Pumps is a UK-based product brand specializing in sealless magnetic drive centrifugal pumps for hazardous, high-value, and high-purity fluid handling. The company's core technology uses magnetic coupling to transmit torque from the drive motor to the impeller without mechanical seals, eliminating emissions and leaks at the primary failure point of conventional sealed pumps. HMD pioneered this technology over 70 years ago and was later combined with the American company Kontro under Sundyne to form the HMD Kontro brand; Sundyne was acquired by Honeywell in 2024.

The product portfolio is split into two specification families: API 685 / API 610 compliant petroleum pumps (GSP, GSPV, LMV 801S, GSPLF, GSPX, HPGSP, GSPVS) for hydrocarbon processing, refining, petrochemical, midstream natural gas, and offshore upstream applications, and ASME/ANSI B73.3 and ISO 2858 compliant general-service pumps (GS in Frame 0/1/2, GT, HPGS, CS, SPGS) for chemical processing, chlor-alkali, fine chemicals, pharmaceutical, and general industrial service. Sundyne engineers defined and established the API 685 standard for sealless magnetic drive pumps, giving HMD Kontro a standard-defining position in its category.

HMD Kontro generates revenue through unit sales of capital pump equipment plus an aftermarket stream of genuine parts, conversions and rerates, gearbox upgrades, service contracts, and SundSCHOOL training. The company operates an enterprise field sales model with multi-year, quote-based contracts, complemented by a global authorized representative network accessible through Sundyne's partner locator system. Customers are process engineers, operations managers, and procurement functions at chemical, petrochemical, refining, midstream gas, pharmaceutical, and offshore oil and gas operators.

Revenue model

1. Industrial Pump Sales: HMD Kontro generates revenue through the sale of sealless magnetic drive centrifugal pumps. Products range from General Service Petroleum (GSP) API 685 pumps to standard chemical service (CS) pumps, with varying specifications for flow rates (up to 3,647 gpm), heads (up to 1,146 ft), power ratings (up to 535 HP), and temperature ranges (-40 to 850°F).
2. Aftermarket Parts and Services: Revenue generated from HMD Kontro Genuine Parts, service and support, conversions and rerates, gearbox upgrades, and training through SundSCHOOL. The sealless design eliminates seals to replace, reducing spare parts inventory for customers while maintaining service revenue streams.

Core offering

HMD Kontro manufactures sealless magnetic drive centrifugal pumps designed to move hazardous, toxic, flammable, corrosive, and high-value process liquids safely without mechanical seals. The product portfolio includes API 685/610 compliant petroleum pumps (GSP, GSPV, LMV 801S, GSPLF, GSPX, HPGSP, GSPVS) and ASME/ANSI B73.3 and ISO 2858 compliant chemical/general service pumps (GS Frame 0/1/2, GT, HPGS, CS, SPGS), serving chemical processing, hydrocarbon refining, petrochemical, pharmaceutical, and upstream oil and gas industries.

Product overview

HMD Kontro offers a comprehensive portfolio of sealless magnetic drive pumps, a technology the company pioneered over seventy years ago. The product line is organized into two main categories: API 685/610 compliant petroleum pumps (GSP, GSPV, LMV 801S, GSPLF, GSPX, HPGSP, GSPVS) designed for hydrocarbon processing, refining, petrochemical, and midstream natural gas applications; and ASME/ANSI B73.3 and ISO 2858 compliant general service pumps (GS in Frame 0/1/2 sizes, GT, HPGS, CS, SPGS) for chemical processing, pharmaceutical, and general industrial applications. All HMD Kontro sealless magnetic drive pumps eliminate seal-related emissions and leaks, making them suitable for handling toxic, lethal, carcinogenic, flammable, and corrosive process fluids.
