For many water transfer and drainage applications, reliability and simple automatic control matter more than complex system design.
The Onga Dominator 75-35 is a 4" single phase submersible pump supplied with a PressController, allowing the pump to start and stop automatically based on demand.
This setup is commonly used where a straightforward, dependable pumping solution is required without the need for external float switches or manual operation.
What this is used for
The Onga Dominator 75-35 with PressController is used for clean water transfer and drainage applications.
- Water transfer from tanks, pits, and sumps
- Domestic and light commercial drainage
- Automatic pump operation based on demand
- Applications where simple on/off control is preferred
What to check before you buy
-
Power supply: Single phase power required.
-
Pump diameter: 4" submersible design. Confirm installation space is suitable.
-
Control method: PressController provides automatic start/stop but does not regulate pressure like a variable speed system.
-
Water quality: Designed for clean water. Debris or solids may require pre-filtration.
-
Duty point: Confirm required flow and head match the pump’s performance curve.
Important control note
The PressController allows automatic operation based on flow and pressure but does not provide constant pressure control. If stable pressure is required, a different control solution may be more suitable.
