Water pressure tanks with pumps for core drilling rigs and floor grinders
Wet drilling and wet grinding require pressurised water, and on a building site the nearest tap is often three storeys away. A water pressure tank with a pump delivers the water to the machine: a 60-litre model on wheels with a pressure pump, or 10- and 16-litre models with a hand pump attached to a carrying strap. All our water pressure tanks have a Gardena coupling on the hose, making them compatible with our core drilling rigs, core drilling systems and floor grinders.
Pressurised water tanks: how the water supply works
During wet drilling, the diamond segments of the drill bit require a constant film of water: this cools the bit, flushes cuttings out of the cut and binds the dust. A pressurised water tank supplies this from the reservoir. With the piston-type hand pump, you pump up the tank until the pressure is sufficient; a pressure relief valve limits the pressure, whilst the vent valve depressurises the tank after work. With the electric pressure pump, a pressure regulator maintains a constant pressure; the display shows the pressure, and the pump is protected against running dry if the tank runs empty.
Pressure pump, battery-powered pump or hand pump
| Water pressure tank | Volume | Pump | Hose | Empty weight |
|---|---|---|---|---|
| WTK 10 and 16 | 10 / 16 l | Piston hand pump | 3 m | Plastic tank with carrying strap |
| WT-60 | 60 l | Pressure pump, 12.5 l/min at 2.4 bar, 230 V or 18 V battery | 3 m | 19 kg, set of wheels |
| WT-60 /S | 60 l | Pressure pump, 12.5 l/min at 2.4 bar, 230 V or 18 V battery | 10 m on a reel plus 3 m | 23 kg, wheel set |
The hand-operated pump tank is designed for individual drill holes and the hand-held core drill; it is carried upright and requires no electricity. The 60-litre tanks are designed for a full day’s work on the Core drilling rig or Floor grinder; the pump runs on mains power or an 18 V battery, with lower pressure extending the runtime when running on battery power. The WT-60/S’s hose reel keeps the hose clear of drilling mud and extends 10 m into the room.
Connecting the water pressure tank to the core drilling rig
Connect the hose to the Gardena coupling on the machine’s water inlet, open the ball valve on the machine’s water inlet, switch on the pump or fill the tank. When drilling into ceilings, a water collection ring catches the water on the wall and directs it into a bucket or wet vacuum. After finishing work, empty the tank and open the vent valve; store frost-free in winter.
Why choose water pressure tanks from Kernlochbohrer.com
Our water pressure tanks are designed to fit our machines; the Gardena coupling fits onto the core drill and the Floor grinder without the need for an adapter. Over 5,000 professionals trust us, and we are Trusted Shops certified. We’ll let you know over the phone, by email or via WhatsApp whether a hand pump or a 60-litre tank is sufficient for your job.
