Arohan Seals is one of the trusted Multi Spring Unbalanced Mechanical Seal Manufacturers in South Africa, offering an array of precision-engineered mechanical seal solutions for pumps, compressors, mixers, agitators and industrial rotating equipment for various industries.
Multi Spring Unbalanced Mechanical Seals are high-quality mechanical seals crafted with the most modern machining technology, high-quality raw materials, and strict manufacturing standards, allowing them to achieve superior sealing performance and long-term use. These seals are designed to ensure even face pressure, smooth shaft movement and good leakage control in low- to medium-pressure industrial applications and are built with multiple evenly positioned coil springs.
For various shaft diameters, temperature ranges and industrial conditions, we are able to make a variety of sealing configurations, such as Rotary Multi Spring Seal, Stationary Multi Spring Seal, O-Ring Pusher Type Seal, PTFE Wedge Type Seal and Utility Pump Multi Spring Seal.
Our sealing systems are used for economical and reliable operation in industries like HVAC, pharmaceutical utilities, water treatment plants, chemical transfer systems, light manufacturing and utility pumping. The engineering team is responsible for precision production, detailed quality inspection and custom sealing solutions, enabling the equipment to work smoothly with fewer maintenance requirements.
The Multi Spring Unbalanced Mechanical Seal is a rotary shaft sealing device which is used to seal the gap between the rotating shaft and the stationary equipment housing of industrial pumps, compressors, mixers and process machinery to prevent fluid leakage. It is a seal that is operated with a number of small coil springs evenly distributed around the shaft to provide a uniform closing force against the seal faces.
Unlike balanced mechanical seals, unbalanced mechanical seals let the process fluid pressure directly impact the seal faces. Such applications as economical sealing performance in low- and medium-pressure clean fluid are therefore well suited for these seals. One seal face rotates with the shaft while the other is stationary and is held firmly within the equipment housing. A thin lubricating film is found between the sealing faces of the seal during operation to reduce friction and heat generation.
A multi-spring arrangement ensures stable sealing during:
The small size and low-cost design make Multi Spring Unbalanced Mechanical Seals ideal for use in applications involving:
The seals come in a variety of configurations depending on the industrial application needs.

Technical guidance before & after purchase
The right material pairing directly determines how long a seal lasts and whether it handles your process fluid without failure. Below are the materials available for this seal type — we select or recommend based on your application.
Self-lubricating with good chemical resistance. The standard rotating face material for general-duty and water pump applications.
Exceptional hardness, wear resistance, and chemical compatibility. The preferred mating face material for demanding applications.
Springs, glands, sleeves, and retainer components. Corrosion-resistant structural integrity across all seal types.
Standard O-ring material for oils, fuels, and general water service. Temperature range: -40°C to +120°C.
Excellent resistance to hot water, steam, and dilute acids. Used where NBR would swell or degrade.
Material selection depends on your process fluid, temperature, pressure, and shaft speed. Contact our team for a recommendation specific to your application.
