Gemels GSJ swivel joints: how to stop hydraulic hose twisting at up to 420 bar A hydraulic swivel joint lets one side of a connection rotate relative to the other while pressurised oil flows through it. The Gemels GSJ series is rated up to 420 bar, uses a patent-pending ball-free design and delivers low operating torque under pressure. The problem: a twisted hose fails sooner On a harvester head, a grapple rotator or a crane boom, hydraulic hoses are constantly twisted, bent and jer

Hydraulic Oil Coolers – Air and Water Cooling Systems

Hydraulic Oil Coolers – Air and Water Cooling Systems Hydraulic oil temperature has a direct impact on the efficiency and service life of every hydraulic system. Excessive oil temperature accelerates oil degradation, increases wear of pumps, valves, cylinders and seals, and may lead to reduced performance and costly machine downtime. A properly selected hydraulic oil cooler maintains the correct operating temperature, extends component life and improves the reliability of hydra

GEMELS – DNV Marine Certification 2025–2027 for Offshore Applications

What does DNV certification actually mean? GEMELS has once again obtained DNV Marine certification for 2025–2027, covering both carbon steel and stainless steel solutions. This is not just a formality. DNV confirms: compliance with strict marine standards, verified material quality, safety in offshore environments. Why marine hydraulics is different Operating conditions include: corrosion (salt, humidity), constant vibration, high pressure, zero tolerance for fa

Hydraulic quick couplings for agriculture – how to reduce leaks, contamination and downtime in the field

In agriculture, equipment changeovers often have to be carried out directly in the field. Machines work in dust, mud, under load and under time pressure. In these conditions, disconnecting and reconnecting hydraulic lines can create several real problems at once: oil leakage, system contamination, difficult reconnection and unnecessary downtime. This matters not only for the machine itself. In practice, it also means protecting the soil, improving operator safety and maintaining equip

Two-speed hand pumps – when they outperform single-speed hydraulic pumps

Two-speed hand pumps – when they outperform single-speed hydraulic pumps In hydraulic systems, a hand pump is not always just a source of pressure. In many applications, something more is required: a fast cylinder approach followed by high-pressure work under load. This is exactly where two-speed hand pumps offer a clear advantage over single-speed designs. HV Hydraulic two-speed hand pumps, including PM2V5-80 and PM2V5-50, were developed to reduce cycle time, lower operator e
