Manure Pump Repair & Rebuilds
Centrifugal, vertical, and piston manure pumps rebuilt by technicians who work on these systems every day. Pickup, shop work, and reinstall coordinated across California's Central Valley.
Pumps fail. The dairy doesn't wait.
Manure pumps run in the harshest environment on a dairy. Impellers wear, seals leak, gearboxes lose oil, and shafts go out of alignment. When a transfer pump quits, lagoon levels back up. When a flush pump fails, the barn can't be cleaned. Operators need a partner who can diagnose fast, source the right parts, and get the system running again without bouncing through three vendors.
Hands on diagnosis, not parts catalog reads.
Our technicians have rebuilt enough pumps to know what fails first on each platform. We pull the pump, inspect the impeller, shaft, bearings, seals, and gearbox, give the operator an honest assessment, and either repair on site or move it to the shop for a full rebuild. When we put it back in, it stays running.
The scope of work.
- Full pump rebuilds with shaft, bearing, and seal replacement
- Gearbox repair and gearbox replacement
- Impeller and wear plate replacement
- Shaft alignment and runout inspection
- Pickup, shop work, and reinstall coordination
- Documented service history per pump
- Honest 'rebuild vs replace' recommendations
Common issues we fix.
Worn impeller / wear plates
Reduced flow, vibration, or excessive amp draw. Usually fixable with a wear part replacement before it cascades into seal or shaft damage.
Gearbox failure
Oil contamination, bearing failure, or stripped gears. We rebuild or replace, depending on age and condition.
Seal leaks
Mechanical seal failure is one of the most common reasons a pump comes to our shop. Caught early, it's a quick repair.
Shaft bend or misalignment
Often caused by debris strikes or improper installation. We straighten, replace, and realign.
Bearing failure
Heat, noise, or unusual vibration. Replaced as part of any rebuild.
Step by step.
Call or request
Tell us what the pump is doing. We'll triage and schedule.
On-site inspection
Technician checks the unit in place when possible to confirm the failure mode.
Pickup or field repair
Minor work happens on site. Full rebuilds go to the shop.
Rebuild + bench test
Parts replaced, seals reset, gearbox serviced, alignment checked.
Reinstall + startup
Pump goes back in, the operator gets a service report, and we follow up.

Dairy manure pumps are built to move thick, solids-laden slurry. For how these collection and transfer systems work, this overview of slurry manure handling systems from Livestock and Poultry Environmental Learning Community is a useful reference.
