High-precision filling equipment isn’t just about how accurate it is on day one—it’s about how well that accuracy holds up over weeks, months, and years of continuous use. At Hi-Tech Machinery, we’ve seen UBA pumps maintain incredibly tight tolerances over extended production cycles, but like any mechanical system, they benefit from regular maintenance and attention.
In this post, we outline best practices for cleaning, servicing, and simple adjustments to ensure your UBA pump delivers consistent, reliable performance over the long term.
🔧 Why Maintenance Matters
UBA pumps are engineered for volumetric dosing with minimal drift, but even the most robust equipment will eventually show signs of wear if not properly maintained.
Key areas where performance can be affected over time:
Wear of internal components (drive piston, plunger, sleeves, valves)
Residue buildup inside the pump body
Misalignment of mechanical parts after extended use
Chemical interaction with seals or elastomers (where used)
Proactive maintenance helps prevent these issues from compromising your filling accuracy, and also reduce downtime.
🧼 Cleaning Best Practices
Regular cleaning is essential to maintain smooth operation and hygiene—whether you’re changing products or performing routine upkeep.
Recommendations:
* Perform a rinse or flush cycle at the end of production runs. Leaving product to sit within the pump, can cause a lot of problems.
* Disassemble and manually clean wetted components when handling sticky or residue-prone products.
* Use compatible solvents or cleaning agents to flush the system.
Top tip – Ceramic sleeve options can reduce residue buildup and simplify cleaning in challenging applications.
⚙️ Simple Adjustment: Zeroing the Micrometre Block
While UBA pumps do not require calibration in the traditional sense, the micrometre block used in pneumatic models can be adjusted and zeroed to fine-tune the stroke length.
* Regularly check and zero the micrometre block as part of routine maintenance to ensure stroke length settings are accurate
* This mechanical adjustment is straightforward and helps maintain consistent fill volumes without complicated calibration procedures.
🛠 Service Intervals and Spare Parts
UBA pumps have minimal moving parts and durable components, but regular inspection and replacement of wear items are recommended.
Suggested general maintenance schedule:
| Interval | Task |
| After each shift | Visual inspection and rinse or flush |
| Weekly | Check valve or rotary valve cleanliness |
| Monthly | Full disassembly and manual cleaning |
| Annually | Inspect piston and sleeve wear; replace seals if applicable |
We supply genuine spare parts including:
* Pistons
* Sleeves (stainless steel or ceramic)
* Rotary/check valves
* Elastomer seals (if used)
Top tip – Using OEM parts ensures precise tolerances and material compatibility for long-lasting performance.
🔄 Full Overhaul Service: Restore Your Pump to Peak Performance
To support the longevity of your UBA pumps, Hi-Tech Machinery offers a comprehensive full overhaul service. When you return your pump to us, our expert technicians will:
- Completely strip down the pump for detailed inspection
