Drainage pumps made
of stainless steel, INOX
These pumps are designed to meet the tough requirements
from mines, construction sites, landfill sites and other
applications that deal with corrosive water. One application
is in mines where the water becomes caustic and destroys
conventional pumps in matter of days. The pumps may also
be used in applications where saltwater is pumped, like
shipyards, fish farms, construction works in harbours and
offshore projects. All INOX pumps can handle pH values from
2 - 10. They can also be equipped with zinc anodes for extra
protection.

Pumping slurry
Pumping fluids with high solids concentrations is more complicated
than pumping water. To avoid sedimentation in the system you need
to choose the right pump size and dimensions of hoses and pipes. The
concentration of solids together with their size and shape may also affect
pump performance and power requirements and therefore pump choice.
Remember that settled solids might need external agitators, water jets or
mixers to get them back in suspension and allow them to be pumped.
As each application requires its own calculation, we recommend you to
contact your Grindex dealer for more information about slurry pumping.

Grindex Pump School
The school consists of technical articles, intended to help pump users
with common matters in pumping with submersible pumps.
Part 1: Choosing the right pump type for the job
A drainage pump is the most commonly used pump type at
construction sites. It is used for pumping water with less
abrasive solids, like clay. Sand and solids in suspension can
also be pumped, up to the size of the strainer holes (normally
0.3-0.5" / 7-12 mm). As sand is quite abrasive to the pump,
it must not be too concentrated.
Sludge pumps are suitable for pumping water with solids, as
well as for pumping sludge. The solids can be up to the size of
the pump inlet diameter (normally 1.3-3.1" / 32-80 mm).
Pumps made of stainless steel are often used in copper mines,
gold mines and other applications with corrosive fluids. An
Aluminum pump can handle water with pH values from 5-8,
while a stainless steel pump can cope with pH values from 2-10.
Slurry pumps are designed to handle abrasive solids in
suspension, like sand, gravel and concrete, in high concentration.
They are also frequently used to move sand in suspension, i.e.
at a dredging operation. To cope with the abrasives, the
hydraulic parts of a slurry pump are often made of a very hard
metal alloy. For improved performance, bigger slurry pumps
can be equipped with agitator.
Grindex Pump School | 51
Plug and pump
An electrical submersible pump is easy
to use, just plug it in and pump. Several
small pumps, placed where the need is
for the moment, can pump the water
to a dedicated collecting pit through
long hoses. As the smaller pumps only
weights 30-50 lbs (14-25 kg), you can
carry the pump with you as the works
moves to different spots at the site.
In the collection pit, a bigger pump is installed and pumps the water
away from the site. By connecting hoses from several pumps to the pit,
you can easily dewater a large area with just a few pumps.
52 | Grindex Pump School
Part 2: Pump arrangement
Despite the simplicity, there are a few details to consider for optimizing
the pumping:
Arrange the pump so it doesn’t burrow itself into sand or clay. This is a
common problem at construction sites. It can be avoided quite simple
by placing the pump on a bed of coarse gravel or a plank. The pump
can also be hung freely by a rope or chain, or put into a cut-down and
perforated oil drum.
Avoid sharp bend on the hose
As sharp bends, kinks and pinching of the hose are reducing the capacity
of the pump, a lot is won by avoiding those circumstances. Turning the
pumps discharge connection so the hose doesn’t begin with at kink
is easily arranged; it can be fitted vertical or horizontal on almost all
Grindex pumps.
Grindex Pump School | 53
Tandem connection
In order to achieve higher pumping
heads, two or more drainage pumps
can be connected in series. For this
purpose, a series connecting flange
is available as an accessory. It is
important that the hoses are equipped
with check valves, preventing the
pumps from suffering from wear
when the water runs back from high
heads uncontrolled if a power failure
should occur.
Long distance pumping
Tandem connection of pumps can
also be used when the water needs
to be pumped a longer distance. A
simple arrangement can be pumping
the water to a dedicated collection
pit. The pit should be equipped with
another pump, passing the water
on. This technique can also be used
for dewatering a greater area with
several pumps spread out, pumping
the water to a collection pit. The pit is
then equipped with a greater pump,
that pumps the water away from the
site.
54 | Grindex Pump School
Part 3: Sedimentation
The pumped water is often containing solids that cause wear on pumps,
valves and other dewatering equipment. This problem is very common in
mines and tunnel construction sites. When pumping water that contains
solids (like drill cuttings and sand), there is a risk of sedimentation
in the system. A typical symptom is pipes and/or hoses that get filled
with sediment, resulting in capacity losses. When the amount of solids
increases, there is also an increase of wear on the pump.
One way to prevent this is by using sedimentation tanks where the drill
cuttings may settle while the rest of the water is pumped away. The tank
needs to be as close to the source as possible, ensuring that the solids are
pumped as short distance as possible where the solids can settle in peace.
To ensure the efficiency of the sedimentation tank, it needs to have as
big surface area as possible. The more solids present in the water, the
more care should be taken in the design of the sedimentation system.
Grindex Pump School | 55
For applications where solids can not be avoided, there are recommendations for the velocity of the medium in the discharge line:
Mixture
Min. velocity in discharge line
1. Water + coarse gravel 13.1ft/s (4 m/s)
2. Water + gravel 11.5 ft/s (3 m/s)
3. Water + sand
Sand particles < 0.004 in (0.1 mm)
8.2 ft/s (1.5 m/s)
Sand particles < 0.024 in (0.6 mm)
4.9 ft/s (2.5 m/s)
