Frequently Asked Questions

Check:
1) Material compatibility with the specific chemical,
2) Temperature rating matches process,
3) Pump curve covers required flow and head,
4) Seal type is appropriate for the application,
5) Motor enclosure suits the environment,
6) Industry certifications are met.

Initial screening steps:
1) Identify fluid chemical composition,
2) Determine pH range,
3) Check operating temperature,
4) Note solid particle content and size,
5) Define required flow and head,
6) Match to pump material compatibility chart.

It is the critical heart of the fluid transportation system, responsible for moving corrosive chemicals safely and reliably through the process. Its performance directly affects production efficiency, safety compliance, environmental protection, and overall system reliability.

Differences include: ease of disassembly for inspection, availability of spare parts, quality of instruction manuals, modular design for quick repairs, and accessibility of seal chambers. Premium brands offer tool-less maintenance and modular component design.

Corrosion-resistant pumps require more careful maintenance: seal inspections for chemical degradation, material compatibility checks when changing fluids, and specialized replacement parts. However, modern plastic pumps have fewer wearing parts and can be simpler to maintain than metal pumps in corrosive service.

Extreme pH values (strong acids <2 or strong bases >12) significantly reduce lifespan if material is mismatched. Properly selected PVDF or PP pumps maintain 5-8 year lifespan in pH 1-14 range for compatible chemicals. Wrong material selection can cause failure in days or weeks.
