Vacuum Pump Welch MPC 603 E Each

Diaphragm Pump – High Performance Vacuum Pump for Laboratory Applications

The diaphragm pump is a high-efficiency vacuum pump consisting of a robust pump body and a powerful drive motor. The pump casing houses the drive unit and two opposing pump heads, each equipped with a precision-moulded diaphragm and two high-quality working valves. Both pump heads are driven by an eccentric shaft with a connecting rod, ensuring smooth, reliable, and low-vibration operation.

Ideal Applications

This laboratory diaphragm vacuum pump is ideal for use with:

• Rotary evaporators
• Vacuum ovens up to 55 litres and 5 mbar
• Concentrators and other vacuum systems

The single-piece moulded diaphragm delivers improved pressure performance with exceptionally quiet operation. The precision diaphragm design reduces vibration and allows easier cleaning, especially when using the gas ballast function. A new advanced pump head design also provides longer service intervals and lower maintenance costs.

Chemical-Resistant Materials

The pump is manufactured using high-quality, chemically resistant materials for maximum durability and performance:

• PTFE – Form-moulded diaphragms
• PTFE – Pump heads
• PTFE – Vacuum hose
• PEEK – Valves
• EPDM – Seals
• PVDF – Screw fittings

Suitable For

The diaphragm vacuum pumps MPC 303 Z and MPC 603 E are designed for:

• Pumping and compressing neutral and aggressive gases and vapours
• Generating a vacuum down to an ultimate pressure of < 5 mbar
• Use in physical and chemical laboratories
• Industrial and research applications
• Vacuum filtration, vacuum distillation, vacuum drying, and general vacuum technology processes

These diaphragm vacuum pumps provide reliable, oil-free, low-maintenance operation, making them an excellent choice for demanding laboratory and industrial environments.
