The Welch MPC 303 Z diaphragm pump offers robust performance, higher speed and efficient operation tailored to industrial needs. Explore our diaphragm pumps category for the full range of products.

Versatile pump for chemical applications

The new WELCH MPC 303 Z comes from our latest pump generation series With up to 20% higher pumping speed in the application critical working range (<20 mbar), more in line with the performance of a 3-stage diaphragm pump.

The oil-free design ensures a clean workplace environment and uncontaminated pumping of gases resulting in cleaner samples with no risk of oil back-streaming, as well as low maintenance costs and very easy serviceability – even simpler than previous generations of pump. Its compact, lightweight design allows for minimal bench space usage and, along with its quiet operation, makes MPC 303 Z the essential chemistry diaphragm pump for laboratories & universal application.Use vacuum regulator with dial gauge (700458) to optimize the vacuum level for the solvent being evaporated. Also available as MXPC 303 Z fully accessorised model.

Improved performance and exceptional reliability

MPC 303 Z has optimised single piece diaphragm (SPD) design and pump head geometry for improved flow path and reliability. With its market leading design using PTFE and other fluoropolymers for all wetted parts, MPC 303 Z is fully chemically resistant against aggressive solvents and acidic vapours commonly used in chemistry and pharmaceutical labs. The pump heads are made from PTFE-carbon fibre composite to offer the best chemical resistance with added strength and rigidity.

Your benefits:

  • Pump a wide range of solvent and acid vapours
  • Improved ultimate vacuum – evaporate high boiling point solvents
  • Perform more work – up to 30% faster process times

Applications:

  • Ideal for evaporation type applications – especially benchtop rotary evaporators
  • Vacuum concentrators
  • Small vacuum ovens

Scope of delivery: Chemical duty diaphragm pump, ON/OFF switch, motor overload protection, DN8 hose nozzle adapter, carry handle and vibration isolating feet. Schuko and UK plug leads
