Speck P45 60 250 75 180 85 160 120 80 L

Summary

Product identification

• Type: High-Pressure Plunger Pumps
• Series: P45

Operating limits

• Max. Pressure:
  • P45/60-250: 250 bar
  • P45/75-180: 180 bar
  • P45/85-160: 160 bar
  • P45/120-80: 80 bar
• Max. RPM: 1000 min⁻¹ (all models)
• Max. Water Temperature: 40 °C (all models)
• Operation: Data are for intermittent operation. Data for continuous operation are available on request.
• Safety: A safety valve must be installed to ensure the admissible operating pressure is not exceeded by more than 10%. Exceeding temperature or speed limits automatically voids the warranty. Particular care must be taken to avoid cavitation, especially when pumping warm water.

Feed water

• Suitable Media: Clean water and other non-aggressive or abrasive media with a specific weight similar to water.
• Other Media: Prior to pumping any other media, a check must be made to determine suitability and resistance of the pumps, considering pump performance and temperature values.

Product water

• Max. Output:
  • P45/60-250: 57.0 l/min
  • P45/75-180: 74.5 l/min
  • P45/85-160: 85.5 l/min
  • P45/120-80: 123.1 l/min

Electrical

• Power Consumption:
  • P45/60-250: 29.1 kW
  • P45/75-180: 27.4 kW
  • P45/85-160: 27.9 kW
  • P45/120-80: 20.1 kW
• Power Calculation Formula: P (bar) x Q (l/min) = kW / 475

Mechanical / hydraulic

• Plunger Diameter:
  • P45/60-250: 24 mm
  • P45/75-180: 28 mm
  • P45/85-160: 30 mm
  • P45/120-80: 36 mm
• Stroke: 42 mm (all models)
• Approx. Weight: 52.5 kg (all models)
• NPSH Required:
  • P45/60-250: 7.9 mWs
  • P45/75-180: 8.6 mWs
  • P45/85-160: 8.9 mWs
  • P45/120-80: 7.9 mWs
• Construction Characteristics:
  • Crankcase of solid sphero-cast-iron ensuring stability and vibration dampening.
  • Crankshaft and taper roller bearings together with plain bearing con rod all run in oil.
  • Solid ceramic plunger.
  • All gaskets in seal sleeves ensuring precise centring and easy replacement.
  • Identical suction and discharge valves, easily accessible.
• Materials Used:
  • Valve Casing: Bronze
  • Plunger: Solid ceramic
  • Valves: High-Grade Stainless Steel
  • Sleeves: Nitrile with fabric reinforcing
  • Crankshaft: Drop-forged and case-hardened
• Installation Notes: Even though pumps run almost pulsation-free, a pressure accumulator may be necessary depending on the unit's construction and operating conditions. Flexible pressure lines can also achieve a similar effect.
