Long barrel 4STM4/8-1.1u ALBASTRU

The submersible pump is designed to extract water from wells, wells and other water reservoirs, for irrigation equipment and systems, as well as for pumping rainwater, tap water and water containing chlorine. It is also designed for domestic water supply in gardens.

The submersible water pump GF-0709-S001-G02 must only be used for pumping water. The pump is fully submersible (by watertight encapsulation) and is submersible in water (for the maximum submersion depth specified in the description). The pump is equipped with a built-in check valve, which prevents the pump from disengaging when the pump is switched off.
This submersible pump can also be operated in a hydrodynamic mode. Add an expansion vessel, pressure switch, pressure gauge and a direction or presscontrol valve to the pump installation.
Multistage submersible pumps have increased sand resistance because they have floating centrifugal blades!
The pumped fluid must be within the temperature range 0-35° C. Discharge head is up to 53 metres.
This model of pump is characterised by multiple qualities such as small diameter, low weight, sturdy casing, high flow rate and corrosion resistant. With this pump the problem of water extraction from deep wells is solved.

The multistage submersible pump is equipped with built-in directional control valve, impeller and diffuser - all made of thermoplastic PPO.
The multistage submersible pump has 8 pumping stages and a common motor and pump housing.
In terms of construction the pump has three main components: the electric motor, the pump and the sealing elements. The pump includes the centrifugal impeller located at the top of the pump motor. They have seals between the pump and motor and O-rings that are used at the joints.

The main feature of a submersible pump is the maximum discharge head as they only work when immersed in the fluid to be pumped. If you want to buy a submersible pump, you need to consider in particular the pumping head (how many metres you want the pump to "lift") and the required water flow rate. The electricity consumption of the pump is directly proportional to the lift height.
It is advisable to choose a submersible pump that is more powerful than the calculations, so that it does not have to operate at maximum load.

Customer benefits:
-Easy to install;
-easy to manoeuvre;
-light weight.

Advantages Tun long 4STM4/8-1.1 u blue Small Farmer:

Before immersing the electric pump in the working position, make sure that there is no sand or solid sediments. If there is, clean the pump site thoroughly. The pump operates in vertical position.

Contraindications in use:
Multistage submersible pumps cannot be used to transfer dirty water containing suspended solids, sand, water containing acids or corrosive substances, sea water, flammable and generally dangerous liquids.

WARNING! We do not recommend the use of this submersible pump to remove dirty, sandy, muddy, gravel water.
