A durable drain cleaner
The pipe pushing unit located at the end of the boom is close to the pipe to be cleaned so as little pushing force as possible is wasted. The boom is strong enough to keep the unit in place without supporting it to the ground. The stainless-steel tube bend is durable and don’t need service because it doesn’t have moving parts. The cleaning hose is 300 m long and can be extended to 400 m. The high-pressure pump gives 50 bar pressure but recommended cleaning pressure is 40 bar. The nozzle has 6 holes backwards and one forward. If there are hard stops in the pipes you can use a nozzle with only four holes backward and a larger hole forward. The nozzles give 65 L at 40 bars.
Filling the water tank with the boom
Filling the Water tank is easy when using the work boom to hold a hydraulic pump. With the extension the pump can be stretched 8 m to reach for water. When keeping the pump just beneath the surface it does not suck mud from the bottom. With Purmets 3” pump it takes about 4,5 minutes to fill the 6500L tank.
Excavation bucket
Sometimes there is damaged drainpipes or underground wells that needs to be dug up. The hose pushing unit can be exchanged to an excavation bucket in just a few minutes.
Digital pipe length counter connected to radio control
From the 2023 model the hose length counter is digital and integrated with the radio control unit. There is a display showing the hose length on the pushing unit. On the radio controls display both length and speed are shown. Eaven a max length counter shows the length of the last pipe for easier documentation of the cleaning result. The radio-control can also be connected to the tractor to start the PTO running the water pump.
Skid-alert
If the hose pushing wheels are skidding there is an alert sound so you can stop the pushing before it damage the hose. Skidding is also prevented by using easy mode on the hydraulic system. If more pushing force is needed just turn the valve to power mode.
Air-injector
Unique for Purmet Drain cleaners is the mixing of air into the cleaning water. When the air bubbles expand thru the nozzle it gives extra power to the jet.
Well
When cleaning pipes thru a well a narrower bent pipe can be used. An extension can be used in deep wells. The well can be emptied with the same pump that is used to fill the water tank. Purmets submersible pump has rubber wings on the impeller so gravel does not get stuck between the impeller and the shell.
