Bombas De Diafragma

A IR DRIVEN DIAPHRAGM PUMPS
FOR SLUDGE AND SLURRY APPLICATIONS

DESIGNED FOR HANDLING HEAVY
SLUDGES AND SLURRIES IN INDUSTRIAL
AND MUNICIPAL APPLICATIONS

The rugged construction and extra-thick pump
casing of Gorman-Rupp air driven diaphragm
pumps stand up to the abuses of the most
demanding sludge and slurry applications.
They overcome the “high-wear” problem
commonly found indouble diaphragm and
progressive cavity pumps.
Air driven diaphragm pumps are capable of
operating dry, on suction lifts up to 20 feet
(6.5 m) and handling high solids contents up to
approximately 70%. Depending on pump
model, they will pass up to 3" (76 mm) diameter
spherical solids. (Solids size is determined by
check valve type.)

4" (100 mm) pump handling
wastewater in a sumpapplication at
a concrete plant in the Netherlands.

4" (100 mm) pump handling
abrasive glass slurry at a glass
manufacturing facility in Ohio.

Pump stroke rate, discharge stroke time, suction
drive pressure and discharge drive pressure
can all be adjusted independently. Pumps will
easily handle heavy sludges at their rate of
accumulation in clarifiers and settling basins.
When it comes tohandling heavy sludges
and slurries, there’s only one name you need to
know — Gorman-Rupp.

TYPICAL APPLICATIONS
Alcohol Plants

Cement Plants

Plating Plants

Pumping various vegetable slurries
(specifically: potato, corn and grains).

Cement wastes, concrete wastes (from
sumps normally).

Chemical transfer, chemical wastes,
heavy metals waste transfer.

Ammunition PlantsChemical Plants

Potable Water Treatment

Heavy metals slurry to filter press.

Chemical wastes, acid reclamation,
acid transfer, sodium hydroxide
(neutralization), filter press feed
(clarifier acidic underflow: waste acid
with solids), solvent recovery.

Alum sludge, lime, and filter back-wash
(charcoal fines).

Auto Plants
