Speck P55G L

PDF datasheet mirror for Speck P55G L (Speck Pumps). Verify with OEM before design.

Summary

Product identification

  • SPECK TRIPLEX High-Pressure Plunger Pumps, Series P55.
  • Available models: P55/80-250G, P55/100-200G, P55/128-160G, P55/150-130G, P55/165-100G.
  • Special versions P55/165-100RE and P55/128-160RE are available with valve casings and wetted parts of stainless steel AISI 316Ti and an integrated drip-return.

Operating limits

  • Maximum Water Temperature: 60 °C
  • Maximum Operating Pressure: Varies by model, see table below.
  • Maximum RPM: Varies by model, see table below.
  • NPSH Required: 8.5 mWs or 9.0 mWs, see table below.
  • A safety valve must be installed to prevent the admissible operating pressure from being exceeded by more than 10%.
  • Cavitation must be avoided.

Feed water

  • Suitable for pumping clean water and other non-aggressive or abrasive media with a specific weight similar to water.
  • Prior to pumping any other media, a check must be made to find out whether these pumps are suitable, taking pump performance and temperature values into consideration.
