Q1｜Parallel vs. Series – How to Choose?
Parallel Mode: Both pump heads work in parallel, prioritizing high flow (typical 60 L/min) with moderate vacuum (around –85 kPa). Best for large-volume gas exchange or rapid purging.
Series Mode: Pump heads are connected in series, prioritizing deep vacuum (up to –98 kPa) with lower flow (around 40 L/min). Best for high-vacuum suction and leak detection.
Rule of thumb: Use series for throttled/high-resistance systems; use parallel for large-volume/low-resistance systems.
Q2｜How to switch between parallel and series quickly?
Install two 3-way solenoid valves or a dedicated “parallel/series” switching valve. Add check valves near each pump head to prevent backflow. During switching, reduce speed or stop the pump for 1–2 seconds to minimize pressure shocks and diaphragm stress.
Q3｜How does performance change with system back pressure?
The P–Q curve is relatively steep: as differential pressure rises, flow decreases, but vacuum/pressure stability is maintained. In low-resistance systems, flow is maximized but vacuum drops. Always ensure at least 20% safety margin at the target operating point.
Q4｜How is continuous operation and heat management ensured?
The motor and pump body are designed for >8,000 hours continuous duty at ambient –10 to 45 ℃. Recommendations:
Keep ≥20 mm clearance for natural cooling.
Use an aluminum baseplate or forced-air cooling in heavy-load applications.
Align airflow direction with cooling fins to avoid heat recirculation.
Q5｜Can the pump handle humid or condensate-laden gases?
It tolerates low-humidity gases. For moisture-rich gases, install a condensate trap/separator and 5 μm filter at the inlet. Ensure the medium and pump body temperatures are balanced to prevent condensation. Continuous water hammering will shorten diaphragm life.
Q6｜How to select diaphragm/valve materials for corrosive gases?
EPDM (standard): Alcohols, aldehydes, some polar media.
FKM: Hydrocarbons, aromatics, solvent oils.
PTFE: Strong corrosives, mixed acids/bases, aggressive solvents.
For complex media, provide MSDS or chemical list for compatibility evaluation.
Q7｜How is pulsation controlled? Do I need a damper?
The dual-head design already reduces pulsation. For higher stability/noise reduction, add a pneumatic accumulator (5–10× stroke volume) or microporous silencer at the outlet. Use flexible tubing + vibration isolators to reduce structural resonance.
Q8｜What about electrical and EMI/noise control?
For 24 VDC supply, reserve 3–4× rated current for startup.
Use twisted/shielded wires, add LC filters & TVS diodes at input.
Ensure proper grounding and separation from weak signal lines.
For speed control, use voltage regulation or PWM >20 kHz (outside audible range).
Q9｜Installation direction & NPT connection precautions?
Installation orientation is flexible; best to keep pump head horizontal, piping downward to avoid condensate accumulation.
Ports: NPT 1/4 – use PTFE tape, tighten “hand-tight + 1–2 turns.” Avoid over-torque to prevent cracking.
Mount with anti-vibration pads; tighten bolts to secure without deforming the housing.
Q10｜Noise levels & on-site optimization?
Noise varies with mounting and piping resonance. Optimize by:
Using ≥300 mm flexible tubing on inlet/outlet.
Adding damping mats inside thin enclosures.
Installing silencers or flow dampers.
For reliable data, use 1 m A-weighted sound measurement under actual installation conditions.
Q11｜How do altitude and environment affect performance?
At higher altitude, air density drops—flow and cooling capacity decrease by ~5% per 1,000 m. In dusty/corrosive environments, add filters/protection and shorten maintenance cycles.
Q12｜How to verify leakage and system tightness?
Use pressure decay or tracer gas (helium/leak detector) testing. For most analytical/sampling applications, aim for leak rates ≤10⁻³ mbar·L/s (or equivalent pressure drop/time).
Q13｜What is the maintenance strategy and replacement cycle?
The pump is oil-free and lubrication-free. Typical life: 8,000 h with clean media. For harsh gases/high load, inspect diaphragms, valves, and bearings every 3,000–5,000 h or annually. Keep OEM service kits available to minimize downtime.
Q14｜Compliance and restricted uses?
The pump complies with RoHS/CE (certificates upon request). Not certified for oxygen-rich, explosive, or ATEX environments. For medical devices, final system compliance (e.g., MDR, UL) must be handled by the device manufacturer.
Q15｜Can the pump be used for both suction and pressure?
Yes. It operates within –98 kPa vacuum and ~2 bar positive pressure. For dual-function systems, use a solenoid valve matrix with safety relief valves to prevent overpressure or misoperation.
