Best Pump for Pig Farm & Livestock Wastewater

We just shipped a batch of pumps out to a pig farm, and it reminded me how often we get this exact question: “Which pump actually survives on a livestock farm?” It’s a fair question, because pig and cattle waste is one of the nastiest things you can ask a pump to move.

So let me walk through what actually matters, based on what our customers run day to day.

Why farm wastewater eats ordinary pumps

Manure slurry isn’t clean water. It’s a mix of solids, straw, hair, bedding, undigested feed, wash-down grit, and a lot of stringy fibrous material. Two things go wrong with a normal pump:

1. It clogs. Fibrous solids wrap around the impeller until flow drops to nothing.
2. It corrodes. Manure is chemically aggressive — ammonia, organic acids, the works.

If you’ve replaced a pump every season on a farm, this is usually why.

Option 1: Self-priming pump mounted above the pit

For most pig and cattle operations, the pump sits next to or above the collection pit, not down in it. That’s where a self-priming design shines — it draws the slurry up on its own, no need to submerge the motor.

Our ZWL direct-coupled self-priming sewage pump is built for exactly this. A couple of points that matter on a farm:

• The impeller mounts straight on the motor shaft — there’s no intermediate coupling to align or wear out. Fewer parts, quicker to install, less to go wrong.
• It’s a non-clog design, so it passes the solids and fibers in slurry instead of jamming on them.
• Because it’s not submerged, servicing it is a dry, above-ground job — no fishing a pump out of a pit full of waste.

This is the one we shipped to the pig farm, and it’s the one that gets reordered.

Option 2: Cutter pump when solids are really bad

If your waste stream has a lot of rags, thick fibrous mats, or bedding material that a normal non-clog pump still struggles with, step up to a GNWQ cutter sewage pump. It has a hardened cutter disc that shreds solids before they reach the impeller, so stringy material never gets the chance to wrap and choke the pump. On farms with heavy bedding or mixed waste, the cutting action is the difference between “runs all year” and “call the guy again next week.”

Quick way to decide

• Slurry is fluid, pump sits above the pit → ZWL self-priming.
• Heavy rags/fiber/bedding, or the pump is submerged in the pit → GNWQ cutter.

If you’re not sure, that’s genuinely fine — tell us the flow you need (m³/h), the height you’re lifting to, and roughly what’s in the water, and we’ll tell you which one fits. No obligation.
