Frequently Asked Questions (FAQ)
What is the minimum flow rate of the DOP-E pump?
The standard minimum flow rate is 0.001 mL/min, but it can be further adjusted with a special driver. Contact our sales team for ultra-low flow configurations.Can the pump handle corrosive chemicals?
Yes, the pump head can be made of PTFE or PEEK, which offer excellent resistance to most acids, bases, and organic solvents. For highly corrosive fluids, we recommend the PTFE version.How do I control the pump remotely?
The DOP-E supports analog voltage/current control, as well as RS485 Modbus communication. A digital pulse input option is also available for flow-proportional dosing.What is the typical lifespan of the diaphragm?
Under normal operating conditions with clean fluids, the diaphragm can last over 2000 hours. Replacement diaphragms are available as spare parts.Is the pump self-priming?
Yes, the DOP-E has self-priming capability for liquids with low viscosity. A dry-run protection feature is optionally available to prevent damage.Can I use the pump for high-pressure applications?
The standard model operates up to 0.6 MPa. For higher pressure requirements (up to 1.0 MPa), a customized version with reinforced pump head is available upon request.What certifications does the pump have?
The manufacturing facility is ISO9001 and ISO9000 certified. Specific CE or other certifications can be arranged for certain markets – please inquire with our sales team.How long is the warranty period?
We offer a standard 12-month warranty from the date of shipment. Extended warranty options are available at an additional cost.
