Durable sump pump
The GSP0311 Cast Iron Sump
Pump is a durable sump pump
designed to provide a longer
overall product life. It boasts
a new, long-life switch that
has undergone multiple rigorous tests well beyond industry standards. The switch also
is easily replaced, further extending the life of the pump. The GSP0311 is
designed with a silicon-carbide seal that can handle 1/2-inch solids, making it tough enough to handle both effluent and sump applications. Built
with high-quality materials, including a tough cast iron upper body, a solid
plastic underbody and a non-clogging vortex impeller design, the pump is
easy to maintain, reliable and long lasting.

Grit removal upgrade
The HeadCell from Hydro International is a modular, multiple-tray settleable
solids concentrator. Its stacked tray design delivers outstanding grit removal
efficiency by providing a large surface area in a small footprint, making it
ideal for both new and retrofit applications. It can be designed to remove
85-95% of all grit entering the plant and has been adapted for intermittent
operation by incorporating Hydro International’s fluidizing system into the
sump and designing an expanded grit pot collector. The HeadCell operates
continuously without power
to separate the grit. At predetermined periods, according to site conditions, the fluidizing agitates the
collected grit prior to it being pumped to the
classifying and dewatering systems.
Inline check valve
The ProFlex® Style 750 Inline
check valve from Proco Products
Inc. is designed for heavy duty
where elements such as abrasive
slurries or sludge are present. The
enclosed body check valve features a maintenance free design with no hinges or seals to bind or freeze. No external power sources are required. The
internal valve features low head loss with a full port design, which opens
with minimal head pressure, and closes with any back pressure exerted on
the valve. The 750 Series valve is provided with two clean out ports and is
manufactured of Carbon Steel with an Epoxy coating. The bolting dimensions are in accordance with ANSI 125/150# pattern.

In blending and solids
where the fluid contains
fibrous material, the resulting build up on the
agitator’s impeller can deteriorate performance, increase energy costs and
even damage the gearbox bearings and gears, causing costly repair. The
Chemineer RL- 3 Ragless Impeller from NOV prevents build up to eliminate
maintenance costs and downtime, increase performance and extend the
service life of the agitator. Designed with a strong central hub and sturdy
blades, the RL- 3 impeller is capable of handling the loads related to material and flow impingement to ensure reliable operation and long service life.
The high axial flow RL- 3 impeller provides superior mixing performance in
blending and solids suspension applications.
