BIG 1500 – submersible sewage pump with float switch
The IBO BIG 1500 submersible pump with a two-channel impeller is designed
for pumping wastewater and dirty water while simultaneously tolerating contaminants
fibrous contaminants and solids up to 50 mm in diameter. The built-in float switch automatically
controls the pump's operation and protects the motor from starting without water.
Who is it for
-
Industrial plants and factories – the two-channel impeller tolerates solid and fibrous contaminants up to 50 mm, making it suitable for draining industrial wastewater.
-
Construction and commercial facilities – the high flow rate of up to 666 l/min enables large quantities of wastewater or rainwater to be drained quickly.
-
Farms – the pump is used for drainage and irrigation.
-
Installation and service companies – the built-in float switch automates pump operation without the need to install additional control equipment.
Applications
The BIG 1500 submersible pump with a two-channel impeller is designed for pumping
wastewater and dirty water free of abrasive materials such as sand, while tolerating
simultaneously handling fibrous contaminants and solids up to 50 mm in diameter. The pump is designed for
for draining rainwater and surface water as well as wastewater in construction sites,
commercial facilities and factories.
In industrial installations, the pump is suitable for pumping cooling water or
industrial applications, while in agriculture it is used for drainage and irrigation.
The unit operates in a vertical position, with a maximum pumped-liquid temperature of
up to 35°C and water pH ranging from 5 to 9. The BIG 1500 230 V submersible pump achieves a head
a head of up to 14 m at a flow rate of up to 666 l/min.
BIG 1500 pump features
The BIG 1500 pump features a cast-iron construction—the motor housing and impeller housing
made of gray cast iron. The shaft and impeller are made of AISI 304 stainless steel, while the mechanical seal
the mechanical seal operates in a SiC/graphite/NBR configuration.
The two-channel impeller can tolerate solid and fibrous contaminants with a diameter of
up to 50 mm, distinguishing it from typical clean-water pumps. The built-in float switch
automatically controls the pump's operation and provides basic protection against dry running,
and the thermal protection built into the winding protects the motor from overheating.

Frequently Asked Questions (FAQ) – BIG 1500 submersible pump
What contaminants can the BIG 1500 pump tolerate?
The BIG 1500 pump’s dual-channel impeller tolerates solids and fibrous contaminants
with a diameter of up to 50 mm, distinguishing it from pumps intended exclusively for clean water
or slightly contaminated water.
How does the pump protect itself against dry running?
Protection is provided by a built-in float switch that cuts off the motor’s power
when the water level falls below the safe minimum. In addition, the thermal protection
a winding thermal protection system protects the motor against overheating.
How does the BIG 1500 pump differ from the BIG 2200?
The BIG 1500 is powered by single-phase 230 V and has a built-in float switch, thanks to
which enables automatic operation. The BIG 2200 is powered by three-phase 400 V, achieves higher
power, head, and capacity, while control is provided by an external control cabinet
properly selected for the installation.
Is the BIG 1500 pump suitable for industrial applications?
Yes – the pump is suitable for pumping cooling or process water in
industrial applications, while the wide tolerated water pH range (5–9) allows operation with various
types of wastewater. If you have any doubts about selecting the right model, we encourage you to
contact with the technical department.
Where can the BIG 1500 submersible pump be purchased?
Dambat does not sell directly. The BIG 1500 pump is available from partner
retail outlets, installation wholesalers, and authorized online distributors.
What warranty terms apply to the BIG 1500 pump?
IBO – 24 months (2 years) manufacturer’s warranty. Warranty and post-warranty service
provided by Dambat.
