Zenit DG Blue 40/2/G40V A1BM5 Cast Iron Automatic Drainage Pump for Sump Drainage with Vortex Impeller

Draining flooded basements and handling greywater from domestic sources are the documented service duties for this automatic submersible unit. It handles liquid temperatures up to 40°C and is engineered for stationary installation in collection pits. The pre-installed float switch ensures automated start and stop functionality, facilitating unattended dewatering in residential environments.

Performance for this 0.3 kW motor includes flow rates of up to 270 L/Min and a total manometric head of approximately 6 m. Drawing a rated current of 2.3 Amps on a single-phase 240 V supply, the unit maintains stable hydraulic performance during continuous run cycles. This 2-pole induction motor operates at approximately 2900 rpm and includes a 10-meter power cable with plug.

The impeller arrangement features a set-back vortex design with 40 mm free passage through the pump. This hydraulic system provides an open internal path through the discharge port. It is engineered to maintain operational stability in dewatering tasks where particulates are present.

Materials include a cast iron EN-GJL 250 pump body and motor casing paired with an AISI 431 stainless steel shaft. Protection is managed by a mechanical seal in an oil-lubricated chamber utilizing Silicon Carbide and Alumina Graphite faces. The assembly features an in-built overload protector and uses NBR rubber for all internal gaskets to ensure long-term structural sealing.

FEATURES

• Cast iron EN-GJL 250 construction for the pump body provides high resistance to corrosion in submerged duty.
• Integrated float switch provides fully automated start/stop control for reliable management of liquid levels in sumps.
• Set-back vortex impeller configuration provides 40 mm free passage.
• Shaft sealing uses a double system with a mechanical seal in an oil chamber to prevent fluid ingress to the motor.
• Alumina Graphite and Silicon Carbide seal faces provide durability when handling domestic greywater and waste.
• Ball bearings support the rotating assembly for stable mechanical behavior at 2900 rpm speeds.
• In-built thermal protector safeguards the motor winding from damage during demanding automated drainage tasks.
• Standard 10-meter submersible power cable includes a Shuko plug for immediate connection to standard power supplies.
