DAB Italy Pompa Celup Borehole S4 40L

- APPLICATION
S4 are multi-impeller borehole pumps with a water-flled or oil-flled DAB motor capable of providing a wide range of hydraulic performances, designed for water boosting, drawing water from subsoil, gardening and irrigation in civil and commercial applications and for the movement of water in agriculture.
- CONSTRUCTION FEATURES OF THE PUMP
Technopolymer impellers housed in the stage box with stainless steel adjustment rings. Pump liner, shaft, coupling with motor, integrated suction flter and stainless steel cable cover. Suction and delivery supports in micro-cast AISI 304 stainless steel. Removable built-in non-return valve in technopolymer or with stainless steel plate (depending on model). Technopolymer impellers designed to ensure high levels of effciency in accordance with Directive 2009/125/EC (Eco design - ErP) with MEI index ≥ 0.4 for the whole range. They have the ACS certifcate, WRAS and DM174 certifcate are pending approval.
- CONSTRUCTION FEATURES OF THE MOTOR
Pump body can be coupled to 4GG and 4OL motors (4TW or 4GX on request). 4GG is a two-pole asynchronous motor with the parts in contact with water made of AISI 304 stainless steel. The thrust block and bushes are cooled and lubricated with a mixture of water and glycol. Rotor mounted on a Kingsbury type self-centering thrust block capable of withstanding high axial loads. The stator is immersed in thermosetting insulating resin with high heat dissipation capacity and encapsulated in an airtight AISI 304 stainless steel casing.
4OL is a two-pole asynchronous motor with the parts in contact with water made of AISI 304L stainless steel. Cooling and lubrication of ball bearings is ensured by a special liquid approved for contact with food. The rewindable stator is housed in an AISI 304L stainless steel casing fxed with steel pins to the upper support of the motor. Equipped with a carbon-ceramic mechanical seal.
For both motors:
Removable cable connector, ACS, WRAS and KTW certifed cable, motor suitable for use with inverters (30 Hz - 50 Hz). In the 50 Hz single-phase version, the capacitor and manually resettable overload protection are in the electrical control panel (to be ordered separately). In the three-phase version, the protection must be guaranteed by the user
