Pump maintenance for acid transfer: three simple habits

With the right care, plastic acid pumps run trouble-free for years. These are the three habits our service team recommends most often in the field.

1. Check the diaphragm regularly

A diaphragm that shows cracks or swelling is the first sign of failure. Replace it on a schedule based on running hours.

2. Renew the seals

Seals in ball valves and connections harden over time under chemical attack. Renewing them at every service is the cheapest precaution.

3. Flush before long standstills

Acid residue left in the line and pump damages the material while it sits idle. Flush with clean water before shutting down.
