Diaphragm pump WL 1040

waterfor chemicalssolenoid-driven

Product Overview
Compact solenoid pumps are small electromagnetic pumps designed for precise, controlled fluid transfer in space-constrained industrial and OEM applications. The WL 1040 uses an electromagnetic coil and plunger mechanism to deliver repeatable dosing and microfluid transfer with configurable pulse or voltage control.

Key Features
Compact solenoid pumps provide rapid electrical response and accurate metering in a simplified mechanical package. The WL 1040 family supports multiple voltage options and offers configurable duty cycles to match application requirements.

Highlights

• Precision dosing and microfluid transfer for space-critical equipment
• Fast response and flow control via pulse frequency or input voltage adjustment
• Low power consumption and simple mechanical integration
• Suitable for OEM devices, medical equipment, laboratory analyzers, beverage machines and microfluid systems

Advantages & Disadvantages

• Advantages: accurate repeatable dosing, compact footprint for limited-space devices, fast electrical response, simple mechanical design and low nominal power draw
• Disadvantages: pulsating flow due to reciprocating action (may require damping), lower max pressure than some mechanical pumps, sensitivity to particles (requires filtration), reduced performance with high-viscosity fluids, possible overheating if used beyond recommended duty cycle

FAQ (selected)

• Q: Can compact solenoid pumps run continuously? A: Many models are designed for duty-cycle operation; verify the specific model duty recommendations.
• Q: Are they suitable for medical devices? A: Yes, when appropriate wetted materials and certifications are selected.
• Q: How is flow rate controlled? A: By adjusting pulse frequency or input voltage.
• Q: Can they pump corrosive fluids? A: Yes, with compatible materials and seals (e.g., Viton or appropriate wetted-material choices).
• Q: What power supply is required? A: Common variants use DC 12V or 24V; AC options exist for certain models.
