These are the pumps that convert the kinetic energy of the fluid into pressure by transferring it with its growing cross-sectional area. Some volute pumps have a diffuser to control the flow.

The most important point to be considered in volute pumps is cavitation. Cavitation is the situation where the absolute pressure of the liquid in the pump falls below the evaporation pressure under the same conditions. Under these conditions, small gas bubbles form in the liquid. When the bubbles containing liquid vapor and dissolved air in the water come to the region of the pressure higher than the evaporation pressure, they burst violently, puncturing the surface of the metal and reducing the capacity of the pump over time. Therefore, cavitation shortens the pump life and causes noisy operation. It is an undesirable situation for the pump.

-Liquid velocity in the suction line. (High speeds can cause cavitation)

-Liquid temperature. (High liquid temperatures can cause cavitation)

-High pump speeds. (Too high pump speed can cause cavitation)

– Molten gases in the liquid (molten gases in the liquid can cause cavitation)

Volute casing  pumps manufactured by turkish scroll pumps producers are produced with soft seal, GG25 cast iron body and impeller structure. Optionally, there are production options with mechanical seal, bronze impeller and body or stainless impeller and body, depending on the usage area and needs.

Volute casing Pumps manufactured by Turkish volute casing pump producers can be produced with 1450 and 2900 rpm engine options. These are the pumps suitable for the needs between 1 – 300 m³/h according to the motor (KW – HP) and pump structure. Volute pumps are suitable for use in agricultural irrigation, pressurized water supply, booster systems, fire pumps, fire booster systems, evacuation of clean or slightly polluted water that does not contain solid particles, industrial facilities, steam boilers, irrigation systems, high flow water needs as well as many other area.

Volute casing Pump types in general;

• Volute casing Pumps 2900 rpm
• Volute casing Pumps 1450 rpm

There are important points to be considered in the selection of volute pumps;

• What is the maximum height that the pump will reach?
• What is the desired amount of water at the distance that the pump will press?
• What is the slope of the land in pumps used for agricultural purposes, what is the distance?
• If the pump will suck, what is the suction distance?
• Since the pump should not be operated at low pressures in multistage pumps, what is the minimum working pressure of the selected pump?
• Is there any foreing matter like particle in the liquid to be pumped, as this type of pump has a closed impeller, it may cause clogging in the impellers.
• It is necessary to pay attention to issues such as whether there is a suitable installation for the pump suction and outlet size.

Volute casing Pumps produced by Turkish volute casing pump manufacturers are mostly used as fire pumps. They are the pumps that feed the fire system in industrial facilities, hotels, factories and dormitories due to their high flow rate.

While choosing and calculating pumps, pricing is important, but pumps should also be in a way that will serve the entire facility when needed. When choosing a pump, the needs of the facility must be calculated correctly. When choosing for the pump to operate at the optimum point, the pumps, closed valve (zero flow) head should be at most 140% of the rated head value, and the head at 150% flow should not be less than 65% of the rated head. Such pumps can be used for system demands with a capacity of 130% of their rated flow rate, provided that the desired pressure value is met.

The rotation of the pump can be by electric motor as well as internal combustion engines or turbines If a spare diesel pump is not used, the energy supply of the fire pumps will be provided from a reliable source and will be fed independently from the general electrical system of the building.

Volute casing  pumps 2900 Rpm ;

 Volute casing Pumps produced by Turkish water pump manufacturers  can be produced with a soft seal as well as optionally with a mechanical seal. In addition to the production of GG25 cast iron for Volute Pumps, there are also production options as a project-specific pump with Bronze and Stainless impellers according to the need and usage area. Since the volute pumps are designed by being driven by an asynchronous 2900 rpm motor, it is used in industries, hospitals, residential units, hotel pump, public housing pump, hospital pump, booster system pump in mass housing, gas station pump system, pump systems in holiday villages, mall central pump systems, frequency controlled booster systems, industrial facilities pump systems, steam boilers pump, pump systems in municipal social and social facilities, fire extinguishing systems, booster pumps, are produced for use in many other areas besides purpose and pressurized water supply. Our newly designed products are optionally suitable for use in hot water applications up to 120°C.

Volute casing pumps 1450 Rpm;

 1450 rpm pumps have less rotation than 2900 rpm pumps, they have a very long life as the wear on the parts of the pump will be less. Since the volute pumps are designed by being driven by an asynchronous 1450 rpm motor, it is used in industries, hospitals, residential units, hotel pump, public housing pump, hospital pump, booster system pump in mass housing, gas station pump system, pump systems in holiday villages, mall central pump systems, frequency controlled booster systems, industrial facilities pump systems, steam boilers pump, pump systems in municipal social and social facilities, fire extinguishing systems, booster pumps, are produced for use in many other areas besides purpose and pressurized water supply. Our newly designed products are optionally suitable for use in hot water applications up to 120°C.
