DAC- SC/Y AND DAS TYPE SUBMERSIBLE WASTE WATER AND SEWAGE PUMPS

Turbosan DAC-SC/Y and DAS series pumps designed for pumping fluids which contents large solids. They have large range of capacity range and available with large range of powers. Capacity range is 3 - 800 l/s discharge head range is 2 - 60 m and power range is 3 kW 400 kW. There are several models and sizes.

• Domestic and industrial raw sewage water pumping

• Waste water handling plants

• In biologic cleaning plants for pumping active sludge.

• Pumping of floating solids in settlement pools.

• Pumping waste water to active screens

• Pumping industrial and chemical waste water.

• Draining rain water

• All kinds of drainage and dewatering

• Pumping miscannous waters in industrial plants

• Unscreened sewage and other waste water types with high solids concentration Pumps are designed to tolerate large solids ( Ø 30 Ø - 200 mm diameter) without clogging.

• Water with sand content. Maximum grain size ( 20 - 30 mm). Liquid, sand ratio can be maximum % 6. For higher sand concentration preventive provisions must be taken against wear.

• Maximum allowed fluid temperature is 40°C

• Maximum allowed medium density is 1,2 gr/cm3, maximum allowed medium viscosity is 1,5 x 10-6 m2/s. Measures must be taken to lower these values.

TECHNICAL DETAILS :

SUBMERSIBLE ELECTRIC MOTOR: Turbosan DAC series pumps have submersible electric motors operates with 3 phase 380 V power supply. Insulation class of motors is F, protection class is IP 68. Upon request H class insulation is available so as differnet power supply options like diffrent frequency or voltage (60 Hz).

SHAFT SEALING: Between motor and pumped fluid high quality double mechanical seal is used, seals operate in oil chamber. (Up to 11 kW single mechanical seal)

BEARINGS: Rotor is supported by means of two heavy duty ball bearings on upperside and lower side.These bearings are selected to support axial and radial loads. In DAC-Y type bearings operate in cooling oil as a result they do not overheat . In DAS ad DAC-SC types bearings are grease lubricated.

MOTOR OVER HEAT PROTECTION SYSTEM: Stator windings protected against over heat by 120 °C termistors. Two thermistor contacts are connected to cable and and must be connected to the thermistor relay.

WATER LEAKAGE WARNING SYSTEM: An electrode system is used which generates a warning signal in case of water leakage caused by worn out mechanical seal or any other reason. In order to have this system operational it must be connected to the Turbosan STR-1 protection relay.

CABLE CONNECTION: H07RN-F type rubber coated cables with flexible cores used. They are durable against corrosiveness of sewage water. Pumps supplied with 10 m cable as standard. Do not transport pump by pulling the cable.

VOLUTE CASING: Volute casings are with concentric discharge and have large crossection. They are designed not to be clogged by the solid that can pass through impeller. In special applications Flush valve can be fitted to the pump. Pumps can be manufactured with different material types if requested by client or it is needed because of liquid properties.

CAUTION: If the subwersible pump will be stored without operation for long time, it must be operated for short of time every 25-30 days. Submersible pumps manufactured according to CE directive.
