Smaller VCG(e) 305-510 submersible pumps


Submersible VCG pumps, VCGE 305-510, are used for pumping water from construction pits, basements, and shafts. They can also be used during natural disasters to pump water from flooded areas and surfaces. Quite often, they are used to irrigate agricultural land. As submersible pumps, they are useful for emptying pools and tanks. They are suitable for pumping dirty water containing sludge and hard particles of up to 8mm in size. The temperature of the pumped liquid may reach a maximum of 40°C. The pumps are portable, so they are made of aluminum alloy components that are durable and impact resistant.

The pumps are made of aluminum alloy housings and stainless-steel parts. Pump impellers sizes 305, 505 and 510 are made of gray cast iron. They are made with single – or three – phase underwater electric motors in dry design. The components of the pumps are submersible electric motors. The windings of the electric motors are of the dry version with Class F insulation. The pump shafts are sealed with mechanical seals that are resistant to the presence of solid particles in the pumped water. The bearing shields of the 305, 505 and 510 pump motors have double rubber radial seals. There is oil in the oil chambers between the seals, which lubricates the seals. The hydraulic parts next to the fluids are rubberized with a rubber that is resistant to wear and the impact of mineral oils. Pumps are made to order for various voltages and frequencies.

Submersible drainage sump pumps are often used as portable pumps, so the pressure connections are adapted for flexible (rubber) hoses. With such use, it is important that the pumps can be operated without water for a short time. All pumps with single-phase motors are equipped with terminal boxes in which starting capacitors are installed.

Pumps with additional A marking are intended for stable installation. They are equipped with control cabinets that allow the connection of float switches. We supply control cabinets for all pumps made according to customer requirements.
