Gather Metering Pumps, Couplings, and MORE

April 10, 2026  | Alvin, Texas |

Introducing Gather Industrie, a growing partner in Chemac, Inc.’s family of high-quality brands. Gather and Chemac have expanded the metering market with precision metering pumps and high quality quick connects. The high quality metering pumps and specialty quick connectors are in strong demand by researchers, labs, manufacturers requiring precise and robust metering pumps and leak free quick connectors. The following introduces Gather to potential customer unfamiliar with their line and history.

60 Years of GATHER Industrie – Precision Fluid Handling from Wülfrath GATHER Industrie GmbH, headquartered in Wülfrath, Germany, has been a leader in magnetically coupled gear pumps, metering systems, and quick-disconnect couplings since its founding in 1965 by Dipl.-Volksw. Herbert Gather. Starting as a trading company, it evolved into a premium manufacturer with full in-house production, including precision turning and milling to tolerances as fine as 5 µm. Today, with around 50 employees, GATHER delivers “Made in Germany” quality to customers in over 30 countries across chemical, pharmaceutical, food, medical, and process industries.

The company’s core strength lies in handling non-lubricating and aggressive media — from acids and solvents to hot caustic solutions — with hermetically sealed, pulsation-free technology. Certified to ISO 9001 and ISO 14001, GATHER emphasizes process reliability, durability, environmental protection, and customization. Whether for single prototypes or large OEM series, its solutions focus on leak-free operation and long service life.

How GATHER Magnetically Coupled Gear Pumps Work – Hermetic Precision

GATHER’s magnetically coupled gear pumps use a contactless magnetic drive to transmit torque from the motor to the pump shaft, eliminating mechanical seals and ensuring true hermetic sealing. This design prevents leaks of hazardous or valuable fluids while delivering pulsation-free metering ideal for precise dosing.

Gears (nickel-based alloy, PEEK, or PTFE) and slide bearings are engineered for low-viscosity, non-lubricating liquids. Flow rates range from 0.02 l/h to 4,000 l/h with differential pressures up to 20 bar. Materials like stainless steel, Hastelloy®, or titanium handle extreme conditions, and the internal cooling system extends service life. The magnetic coupling also acts as an overload protector by decoupling under stress.

GATHER Quick-Disconnect Couplings – Safe, Dry-Break Fluid Transfer GATHER’s quick-disconnect couplings provide robust, spill-free connections for pipes and hoses carrying liquids and gases. The flagship DBG flat-face dry-break series (DN 4 to DN 80) features shut-off in both halves, preventing drips even under residual pressure. Variants include sterile DBG-CSP (CIP/SIP capable, Ra ≤ 0.8 µm, FDA-compliant) and tanker-specific models.

Operating from vacuum to 350 bar and –120°C to +325°C, these couplings support Hansen Original series (HIG, HK, ST) in stainless steel, brass, or Hastelloy®. Options like color coding, electronic interlocking, and emergency separation enhance safety in chemical plants, pharma, and food processing.

 

Precision Metering in Chemical & Process Engineering with GATHER Pumps In chemical and process plants, GATHER gear and turbine pumps excel at metering aggressive, low-viscosity media without pulsation. Hermetic magnetic drives ensure zero leakage of acids, alkalis, solvents, or hot caustics, supporting continuous operation in reactors, dosing lines, and circulation systems.

Flow rates of 0.6–3,600 l/h and wide temperature spans (–200°C to +450°C for turbine models) make them ideal for high-precision tasks. ATEX-compliant metering systems integrate pumps, controls, and sensors for explosion-risk zones.

 

GATHER Solutions for Pharmaceutical and Cosmetic Manufacturing Pharmaceutical and cosmetic production demands sterile, precise, and contamination-free fluid handling. GATHER’s SIP/CIP-capable gear pumps and sterile DBG couplings deliver pulsation-free dosing of active ingredients, solvents, and creams. FDA-compliant materials and smooth surfaces (Ra ≤ 0.8 µm) meet strict hygiene requirements.

Custom metering systems provide repeatable accuracy for batching and filling lines, while quick-disconnect couplings enable fast, leak-free changeovers between processes.

 

Turbine Pumps from GATHER – Extreme-Temperature Process Reliability GATHER’s magnetically coupled mini turbine (centrifugal) pumps are designed for pulsation-free circulation and metering of low-viscosity fluids across extreme temperatures (–200°C to +450°C). With flow rates up to 3,600 l/h and differential pressures to 5 bar, they handle cryogenic liquids, hot solvents, and everything in between using Hastelloy® or titanium components.

Perfect for cooling circuits, high-temperature chemical loops, and specialized research applications.

 

The New GATHER Gear Flow Meter (ZDM) – Accurate Volumetric Measurement Based on proven gear-pump technology, GATHER’s ZDM gear flow meter delivers precise volumetric measurement for non-lubricating, low-viscosity media. It complements the pump lineup by providing real-time flow data in chemical, pharmaceutical, food, and medical processes.

Compact, robust, and hermetically sealed, it integrates seamlessly into metering systems for closed-loop control.

 

Sustainability and Green Chemistry – GATHER in Hydrogen Production GATHER gear pumps support the green transition by dosing hot potassium hydroxide (up to 90°C) in electrolysis systems for hydrogen production. Their robust magnetic drive and non-lubricating capability ensure reliable, leak-free operation in sustainable energy processes. Hermetic sealing minimizes emissions and product loss, aligning with ISO 14001 environmental goals.

 

Custom Metering Systems – Complete Solutions from GATHER Beyond individual pumps, GATHER engineers complete ATEX-compliant metering systems tailored to customer specifications. These include pumps, flow meters, controls, valves, and accessories for turnkey precision dosing in complex applications. From lab-scale to industrial plants, systems are tested and commissioned in-house for guaranteed performance.

 

Longevity, Maintenance & Why GATHER Technology Lasts GATHER pumps and couplings are engineered for decades of service with minimal maintenance. Magnetic drives eliminate seal wear, while precision “Made in Germany” manufacturing and high-quality materials (Hastelloy®, PEEK, etc.) resist corrosion and abrasion. Quick-disconnect couplings offer over 500,000 cycles. Regular inspection of bearings and gears, combined with genuine parts, keeps systems running at peak efficiency with low total cost of ownership.

GATHER’s focus on durability and process safety makes it the preferred partner for critical fluid-handling applications worldwide.
