Stop replacing pumps that can’t handle the job. Discflo cantilever pumps are built for nonstop duty in harsh sump and tank environments—no submerged wear parts, no clogging, and no breakdowns. Just years of reliable performance in the worst conditions on earth.
“In five years, we’ve never had a pump failure. Every time we’ve inspected the disc pumps, there has been no sign of appreciable wear on the Discpac”
—Dave Polcha, Steel City Pumps
“Our old pump was always underwater. It just couldn’t keep up. It was always clogging from the solids, so that we were going through a pump a week.
We haven’t had to fix the Discflo pump in two and a half years. A pump operating for two and a half years in this application is unheard of.”
—Gery Fletcher, Stelco Corporation
Thick slurries, abrasive waste, and corrosive chemicals destroy most cantilever pumps. Seals fail. Bearings wear out. Downtime eats into your productivity and profits.
Discflo vertical cantilever pumps solve these challenges by design. With no submerged wear parts and our patented Discpac technology, they’re built to handle what breaks the rest.
Instead of impellers or vanes, the Discpac uses rotating discs to move fluid smoothly, without shear or product degradation—even in highly viscous, abrasive, or high-solids environments.
Wide internal passages allow safe handling of slurries containing up to 80% solids and particles measuring up to 20 inches—no clogging, binding, or wear.
All wear parts are mounted above the fluid line to prevent exposure to harsh fluids, extend service life, and simplify maintenance.
Handles dry conditions without damage. Ideal for batch operations, sumps, or variable levels.
Available in rugged alloys like CD4MCu and Hastelloy to resist extreme chemical or mechanical wear.
The Discpac technology ensures steady performance in volatile conditions, including sudden system shocks, pressure changes, and thermal cycling.
Field-tested on harsh coal sludge and corrosive chemical waste. Keeps running where other pumps clog, wear out, or fail continually.
No frequent seal replacements. No impellers to erode. Just fewer repairs, fewer shutdowns, and thousands saved on annual upkeep.
Our pumps regularly outperform conventional submersibles, diaphragms, and other cantilever models. Our units have logged years, even decades, of repair-free services.
Drops into tight tanks and sumps with no alignment or external priming systems needed. Easy to access, even in confined installations.
With motors mounted above fluid level and no seal support systems required, Discflo cantilever pumps offer safer, cleaner, and easier day-to-day operation.
Ideal for pits, tanks, and reservoirs where the motor must remain dry.
Built to move ore slurries, fines, and leaching fluids in abusive conditions.
Handles fluids with up to 80% solids. Perfect for tailings, pulp, grit, sludge.
Safely pumps acids, solvents, and hydrocarbons.
Handles fibrous slurries and viscous paper stock without clogging or downtime.
Pumps sludge, effluents, and abrasive wastewater with ease.
Oily Water Service
Replaced failing vertical lineshaft pumps. Delivered four years of zero-maintenance performance—saving $7,700+ annually per unit.
High-Viscosity Coal Sludge
Replaced submersibles that failed weekly. Ran for 2.5+ years without downtime in coal slurry with baseball-sized solids.
Hot Acid and Steel Slurry
Replaced faulty vertical pumps in a 1,800°F acid slurry line. The result: five years of continuous failure-free service—saving $32,000+ annually in repair costs.
