HYDROSET does not depend on the pump brand. Any single-phase water pump whose current falls within the range of the chosen model will work with it — a domestic peripheral pump, a jet pump, or a multistage pump in a building booster set. It takes the place of the mechanical pressure switch, so you do not need to change the pipework or the pump.
Smart water pump controllers, made in Iran
Pressure Managers are smart pump controllers for domestic water systems, easy to install and equipped with full safety features. HYDROSET holds your building's water pressure steady, starts and stops the pump gently, and is a direct replacement for the mechanical pressure switch.
| Pump current | Pump power | Model |
|---|---|---|
| up to 8 A | up to 1.5 hp | PM821-8 |
| 8 – 16 A | up to 3 hp | PM821-16 |
| up to 25 A | up to 4 hp | PM821-25 |
Frequently asked
Which model fits my building?
Choose by the current on the pump nameplate: up to 8 A (1.5 hp) is PM821-8, from 8 to 16 A (3 hp) is PM821-16, and up to 25 A (4 hp) is PM821-25. If you do not know the current, buildings of one to four floors usually need the 8 A model and buildings of five to ten floors the 16 A model.
Do the products come with a warranty?
Yes. Two years of warranty covering free repair or replacement for any parts or manufacturing defect, plus five years of after-sales service covering parts, repair and technical support.
What happens if the water supply stops?
The controller detects dry running and shuts the pump down before it is damaged, then retries at the interval you set. The error clears by itself as soon as water returns.
Does it work with a pressure vessel?
Yes. HYDROSET works both with and without a pressure vessel, and suits homes, shops and gardens.
Does it replace a mechanical pressure switch?
Yes. It takes the place of the mechanical switch and adds pressure regulation, soft start and stop, and electronic protection on top of it.
How long does installation take?
It is straightforward. The pressure sensor is fitted to the pipe after the check valve, and the incoming supply and pump output are wired to the controller's terminals. Factory settings suit most installations without adjustment.
What pressure should I set?
It depends on building height: about 3.0 bar cut-out and 1.5 bar cut-in for 10 m (3 floors), 4.0 and 2.5 bar for 20 m (7 floors), and 5.0 and 3.5 bar for 30 m (10 floors).
