2. Spend less per gpm pumped
Just like our pumps spend most of their life hidden below the water surface, the greater part of total
pumping cost is usually also hidden. In most cases, installation, operation and servicing costs easily outweigh
the cost of acquisition. Let our pumps drain water, not your wallet.

3. Translating user requirements into product features
After some 50 years of designing and manufacturing submersible electrical dewatering pumps and listening
to customers, Grindex offers a drainage and sludge pump family designed to dramatically reduce operational
costs.
The pumps in the range have an output of 1.3 - 140 HP and cover almost any application within building
and construction, mining, quarries and tunneling as well as municipal and other demanding industries.
They offer all the benefits you have come to expect
from Grindex pumps:
On top of that, we have added some
new features:
• Reliability thanks to:
- Air valve that cools the pump should it run dry.
- SMART motor protection system, protects the
pump from damage caused by different power
failures.
• New hydraulic design:
-
Several solutions that minimize wear, makes
the pumps at least three times more wear
resistant.
• All in the head:
- Built-in start equipment in almost all pumps,
no need for external start equipment.
• Fewer components:
- Makes inspection and service faster, easier and
less expensive.
• Ergonomic design:
- Simplifies the pump handling.
