How to select the right booster pump? (Four key factors)

Selection depends on four factors: ① Media (gas/liquid type — O2, N2, H2, air, hydraulic oil, etc.), ② Inlet pressure (your existing supply pressure), ③ Required outlet pressure (target working pressure), ④ Flow rate (volume per unit time at target pressure). Provide these four and our engineers will recommend the matching model within 24 hours.

Pneumatic-driven vs electric-driven booster pump — which to choose?

Pneumatic-driven (air-driven) pumps use compressed air as power — no spark, explosion-proof, suitable for flammable/explosive environments, lower cost, but require a stable air source (3-8 bar [TBC]). Electric-driven pumps offer higher flow and continuous operation but need electrical power and are not inherently explosion-proof. For hazardous environments (hydrogen, oil & gas), pneumatic is strongly recommended.

What is the maximum pressure SUNCENTER equipment can achieve?

Gas booster pumps: up to 80 MPa (800 bar). Hydraulic/testing equipment: up to 600 MPa [TBC]. Specific maximum pressure varies by model — see each product's datasheet for details.

What media can SUNCENTER booster pumps handle?

Gas media: air, nitrogen, oxygen, hydrogen, helium, argon, CO2, natural gas, etc. Liquid media: hydraulic oil, water (with corrosion-resistant configuration), special chemicals. For corrosive or high-purity media, seal material and wetted parts customization is required — contact us with your media specification.

How is the boost ratio calculated?

Boost ratio = outlet pressure ÷ drive pressure. For example, a pump with a boost ratio of 40:1 driven by 6 bar air can theoretically reach 240 bar outlet. In practice, actual outlet pressure is slightly lower than theoretical due to internal friction and seal resistance. Our engineers will calculate the exact ratio for your application.

Can you customize pumps for special media or extreme conditions?

Yes. We offer customization for: special seal materials (Viton, PTFE, etc. for corrosive media), high/low temperature configurations, high-purity cleaning for semiconductor/gas applications, and ATEX/explosion-proof certifications. Contact us with your requirements for a custom solution.

What are the installation requirements for booster pumps?

Install on a flat, rigid surface with mounting bolts. Ensure adequate ventilation around the pump. Inlet and outlet piping must be correctly sized and supported to avoid stress on pump fittings. Install a filter and pressure regulator on the drive air line. Refer to the model's user manual for specific installation dimensions and torque specs.

What peripheral equipment is needed?

Essential peripherals: ① Air filter + regulator + lubricator (FRL) on drive line, ② Pressure gauge on inlet and outlet, ③ Safety relief valve on outlet line, ④ Shut-off valves for isolation. Optional: buffer tank for pulsation damping, check valve, pressure switch for auto-control.

How to adjust the output pressure?

Output pressure is controlled by adjusting the drive air pressure via the regulator on the drive line. Higher drive pressure = higher outlet pressure (following the boost ratio). Always start with low drive pressure and gradually increase while monitoring the outlet gauge. Set the safety relief valve to the desired maximum pressure.

Can the pump run continuously?

SUNCENTER pneumatic booster pumps are designed primarily for intermittent duty. For continuous operation, we recommend: ① using two pumps in alternating duty, ② ensuring adequate cooling, ③ regular seal inspection. For continuous high-flow applications, consult us to select an appropriately rated model or system.

What is the operating noise level?

Typical noise level is 70-85 dB(A) at 1 meter, depending on model and drive pressure. A silencer/muffler on the exhaust port significantly reduces noise. For noise-sensitive environments, additional sound enclosure can be provided. Specific noise data is available in each model's datasheet.

How is the equipment packaged for shipping?

Standard export packaging: equipment secured in custom wooden crates (plywood/fumigated wood compliant with ISPM-15), with foam padding and moisture barrier. Fragile components (gauges, PLC screens) are individually protected. Crates are marked with handling symbols and product info. Container loading photos are provided to customers.

What is the lead time / delivery time?

Standard models: 15-25 working days. Custom/non-standard configurations: 30-60 working days depending on complexity. Testing equipment and skid-mounted systems may require longer. Exact lead time is confirmed in the proforma invoice after order details are finalized.

What trade terms and payment methods do you accept?

Trade terms: EXW, FOB, CIF, DAP, DDP (negotiable). Payment: T/T (30% deposit + 70% before shipment), L/C (at sight, for qualified customers). Other terms negotiable for long-term partners. Contact sales for specific payment arrangement.

What is the warranty period?

Warranty period is 13 months from shipment date [TBC]. Covers manufacturing defects and non-artificial damage. During warranty, free repair or replacement of defective parts. Lifetime technical support provided. See our warranty policy page for full terms.

How often should seals be replaced?

Seal replacement cycle is typically 15-20 months [TBC · competitor reference · pending validation], depending on operating frequency, media, and pressure. Signs that seals need replacement: pressure drop, visible leakage, reduced efficiency. We provide seal kits (part numbers in the manual) for self-replacement or factory service.

How to request after-sales service?

Contact us via: ① Email (sales@suncenter.com) with photos/videos of the issue, ② Phone/WhatsApp, ③ Submit a service request through the Contact page. Our engineers will diagnose remotely first (video call), and arrange on-site or return-to-factory service if needed. Response within 24 hours.

Do you offer OEM/ODM and on-site installation?

Yes to both. OEM/ODM: custom labeling, modified specifications, private-brand production. On-site installation: available for skid-mounted systems and large equipment [TBC — confirm if included or extra-cost]. Remote video installation guidance is standard and free. Commissioning and training services available.

Which countries do you export to?

We have exported to 80+ countries [TBC] across the Middle East, Southeast Asia, South Asia, Europe, Americas, Africa, and Oceania. Major export markets include India, Vietnam, Thailand, UAE, Saudi Arabia, Turkey, Russia, Brazil, and others. We are experienced in export documentation, customs clearance, and international logistics.
