Installation & Usage Notes
To ensure stable long-term operation, follow these installation guidelines:
Inlet Filtration
Install a ≤30 μm precision filter at the pump inlet to prevent particles from entering the pump chamber and affecting valve and diaphragm performance.
Bottom Mounting
4 × Φ2.4 mm holes (depth 6.8 mm)
Recommended fasteners: M3 self-tapping screws for secure through-board fixation
Side Mounting
2 × R1.7 mm through holes
Use M3 screws for stable installation through the mounting plate
Proper mounting helps reduce vibration transmission and improves overall system stability in OEM integration.
Q1: Why does the pump output fluctuate in some inkjet or dosing systems?
In most cases, flow fluctuation is caused by inlet air leakage, insufficient priming, or improper tubing selection. Ensuring airtight connections and correct inlet conditions helps maintain consistent micro-liquid delivery.
Q2: What causes difficulty in self-priming at startup?
Priming issues usually come from excessive suction height, dry inlet conditions, or missing inlet filtration setup. Keeping suction within the rated range and ensuring a sealed inlet path improves startup performance.
Q3: Why does the pump show increased noise or vibration during operation?
This is often related to unstable mounting, resonance from system structure, or backpressure fluctuations. A rigid installation and stable tubing layout help reduce mechanical vibration.
Q4: What is the delivery time for this diaphragm liquid pump?
Sample delivery is typically 3–5 days. Bulk production lead time is usually 20–30 days depending on order volume and customization requirements.
Q5: Is a brushed version available for this model?
Yes, a brushed motor version is available under model BD-05TF450W, designed for cost-sensitive OEM applications with similar integration requirements.
