Industries — Rendering
Rendering is about as hard as pumping gets: hot, greasy, abrasive, and full of bone and hide. The wrong pump wears out, fouls, or seizes fast. IPE spec's equipment meant for the punishment, from raw intake all the way to finished fats.
The Reality of the Plant
Hot, greasy, abrasive, and continuous — rendering combines every hard condition at once. Four pressures shape every pump selection.
Offal, bone, and grit chew through standard pumps and clog tight clearances. Rendering needs equipment that passes solids and shrugs off wear.
Molten tallow, grease, and oils run hot and thick. The pump has to handle temperature and viscosity without losing throughput.
Blood, DAF sludge, and stickwater are greasy, fouling, and corrosive — hard on seals and hard on standard designs.
Rendering runs around the clock, and raw material doesn't wait. Downtime on one pump backs up the entire plant.
Stream Matching
We carry several lines, so we can put the right pump on each stream instead of forcing one pump to do everything. Here's how a rendering plant tends to break down.
Moving offal, trimmings, bone, and condemned material — high-solids, abrasive, and chunky. Seal-less hose pumps and enclosed transport handle it without clogging.
How peristaltic pumps work →
Gentle, seal-less transfer of blood and coagulating product, where impellers and seals would foul and clog.
How peristaltic pumps work →
Hot, viscous fats and molten tallow moved with positive displacement — steady flow that doesn't fall off as viscosity climbs.
How PD pumps work →
Abrasive, greasy sludge and grease-trap waste moved by air-operated diaphragm pumps that pass solids and tolerate running dry.
How AODD pumps work →
High-flow transfer of stickwater, press liquor, and condensate — thin process streams carrying fats and fine solids.
How centrifugal pumps work →
Plant-scale movement of demanding material at volume — where lighter pumps simply can't keep up.

Working With Us
The company that makes one pump won't tell you when a different one would last longer. We will, because in a duty this rough, the wrong fit shows up fast.
Lamella, Enviroflex, Ampco, VUMP and more, so we can put the right pump on raw intake, on fats, or on wastewater, rather than the stream on whatever we sell.
Lamella is proven in rendering, and everything else we recommend is picked for abrasive, hot, fouling service, not borrowed from a light-duty catalog.
Raw intake, fats, wastewater, enclosed offal transport, and the drives to run them, sourced and matched by one company that has seen the whole flow.
Sizing, application help, and field service across North America, from people who understand how brutal by-product processing really is.
The Lines

Heavy-duty sanitary pumps proven in rendering — six sizes to 14", 10 to 200 m³/h for high-throughput raw-material and process streams.
View the Lamella line →
Seal-less hose pumps and AODD pumps for offal, blood, and DAF sludge — the abrasion- and solids-tolerant end of the line.
View the Enviroflex line →
Rotary lobe for hot viscous fats, centrifugal for stickwater and process water, and the SP liquid-ring for CIP. 3-A and EHEDG.
View the Ampco line →
Enclosed, instrumented offal and by-product transport that moves waste to screening for solids recovery — replacing pumps, augers, and conveyors.

Rendering Questions
Straight answers to what renderers ask most about moving their streams.
What pump handles rendering raw material and offal?
Seal-less peristaltic pumps and AODD pumps, such as Enviroflex, pass high-solids, abrasive offal without clogging, and the enclosed VUMP System moves offal and by-product to screening. For high-throughput lines, heavy-duty Lamella pumps carry demanding material at volume.
How do you pump hot tallow, fats, and grease?
Positive displacement rotary lobe pumps, such as Ampco's, move hot, viscous fats and molten tallow with steady flow that holds up as viscosity rises. For thin, hot process streams, sanitary centrifugal pumps are more efficient.
Can you handle DAF sludge, grease trap waste, and stickwater?
Yes. AODD and peristaltic pumps handle abrasive, greasy DAF sludge and grease-trap waste, tolerating solids and running dry. Thin streams like stickwater and press liquor suit high-flow centrifugal pumps.
What is used for blood transfer in rendering?
Peristaltic hose pumps are ideal for blood and coagulating product. The hose is the only wetted part, so there are no seals or impellers to foul, clog, or shear.
What is the best pump for a high-throughput rendering plant?
Lamella heavy-duty sanitary pumps are built for continuous, high-volume duty, handling 10 to 200 m³/h across the most demanding food and by-product streams.
How do I get help sizing a pump for my rendering line?
Describe the stream, including material, temperature, solids, and flow, and IPE will recommend and size the right line. Call 206-790-0775, email [email protected], or use the quote form.
Tell us the stream and the step — raw intake, tallow, sludge, or wastewater — and IPE will spec the pump to match.
