Hydraulic accumulators
TEFIKS membrane tanks - a reliable solution for water supply and heating systems
TEFIKS hydraulic accumulators are closed-type expansion tanks designed to stabilize pressure in water supply, heating and hot water supply systems. Due to their design, they compensate for water hammer, reduce the load on pumping equipment and ensure stable operation of the entire system.On the website of the company "Ukspar" (Kyiv) presents TEFIKS membrane tanks with volumes from 12 to 5,000 liters, which you can buy with a guarantee and professional advice.
Why is a membrane tank needed in the system?
The main purpose of a hydraulic accumulator is to regulate pressure and provide water supply. Its installation allows:
- avoid water hammer when turning on pumps;
- reduce the number of pump starts;
- ensure stable pressure in the system;
- store a certain amount of water in case of a short-term power outage;
- to compensate for the expansion of water when heated in heating systems.
Main areas of application:
- private houses with autonomous water supply;
- multi-apartment residential buildings;
- commercial properties;
- heating stations and boiler houses;
- pumping stations.
The principle of operation of a hydraulic accumulator
The TEFIKS expansion tank has a steel body, inside which is placed a rubber membrane (pear). It divides the internal volume into two zones:
- water chamber (filled with water from the system);
- air chamber (pre-filled with air).
When the pump delivers water, it enters the membrane, which expands and compresses the air. When the pressure in the system decreases, the membrane compresses back and the water exits, compensating for the pressure drop in the pipeline system.
Simple and reliable scheme:
- The pump supplies water → the membrane fills.
- The pressure increases → the pump turns off.
- Water is used → pressure drops.
- The membrane pushes out water → the pressure stabilizes.
- The pump turns on again when the pressure reaches a minimum.
This process is cyclical and ensures pump life savings and user comfort.
The design of the TEFIKS membrane tank: what it consists of and why it is important
All TEFIKS hydraulic accumulators are designed for durability and resistance to constant pressure drops. They meet technical standards for use in drinking water supply systems, autonomous heating and pumping stations.
Main elements of the membrane tank:
- Carbon steel body, powder coated. Protects against corrosion, mechanical damage and ensures a long service life.
- The rubber replaceable membrane Se.Fa (pear) is the main element that works with pressure. It is made of EPDM food-grade rubber, which is approved for contact with drinking water, is resistant to temperatures up to +100 °C and does not lose elasticity.
- Steel flange - membrane mount and connection point. Equipped with an O-ring and protected against corrosion.
- Air chamber — the space between the housing and the membrane, filled with compressed air.
- Air injection nipple - allows you to adjust the pressure in the air chamber.
- Anti-corrosion coating on the inside (depending on the model) is additional protection for a long service life.
What is inside the TEFIKS accumulator?
Inside the tank is a food-grade rubber membrane that separates water and air. The water only comes into contact with the membrane, not with the metal. Thanks to this:
- corrosion is excluded;
- the tank can be used for drinking water;
- the service life of the entire system increases.
TEFIKS tank volumes: from 8 to 10,000 liters
TEFIKS Fig. TFS-V expansion accumulators are available in a wide range of volumes - from compact models with a capacity of 8–36 liters to large industrial tanks with a capacity of up to 10,000 liters. This allows TEFIKS products to be used both in domestic water supply systems and in complex engineering facilities.
The model range includes
Vertical accumulators without support legs: TFS-V/8, V/12, V/19, V/24, V/36 — from 8 to 36 l, pressure 10 bar, connection ¾" BSP/NPT.
Vertical accumulators with support legs:
- TFS-V/50L – V/1000L — from 50 to 1000 l, pressure 10 bar, connection from 1" to 3" BSP/NPT.
- TFS-V/1500L – V/10,000L — from 1,500 to 10,000 l, pressure 10 bar, weight up to 1,920 kg, connection 3" BSP/NPT.
- built-in pressure gauge in models from TFS-V/150L (from 150 liters) and above.
Each model has precise technical specifications: wall thickness, operating pressure, connection type, dimensions and preset pressure in the air chamber.

What are the advantages of TEFIKS membrane tanks?
Choosing a quality accumulator directly affects the efficiency of the entire water supply or heating system. The TEFIKS brand has established itself as a manufacturer of reliable products.
Key benefits:
- High resistance to pressure drops.
- Compatibility with pumping stations, boilers, and water heaters.
- Wear-resistant EPDM membrane Se.Fa.
- No contact of water with the metal of the case.
- Low pressure loss over time.
- Easy maintenance and air inflation.
- Possibility of replacing the membrane.
What is the difference from other tanks:
- TEFIKS uses a fully sealed membrane, which avoids internal wear and micro-leakage.
- The thickness of the steel casing meets the standards for high pressure operation.
- Quality control of each product - all tanks are tested before shipment.
- Stable operation at temperatures up to +100 °C.
- The availability of models for installation in confined spaces is ideal for apartments, technical cabinets, and boiler rooms.
How to choose the right expansion tank
In order for the accumulator to perform its function without failures, you need to consider:
- Purpose: heating, water supply.
- Installation type: vertical or horizontal.
- Volume: the larger the water supply, the less often the pump turns on.
- Membrane material: only food-grade EPDM is suitable for drinking water.
- System pressure: The tank must withstand the working load.
- Membrane replacement capability: important for long-term use.
The right choice ensures system stability, equipment protection, and reduced maintenance costs.
