Speck P62 50 420R 70 300 L

Summary

Product identification

• SPECK TRIPLEX High-Pressure Plunger Pumps, Series P62.
• Available models:
  • P62/50-420R (Code No. 00.6814)
  • P62/70-300 (Code No. 00.6815)

Operating limits

• Data provided is for intermittent operation; data for continuous operation is available on request.
• A safety valve must be installed in accordance with guidelines for liquid spraying units, set so that the admissible operating pressure is not exceeded by more than 10%. Pump operation without a safety valve, or any excess in temperature or speed limits, automatically voids the warranty.
• Particular care must be taken when pumping warm water, making absolutely sure that cavitation cannot occur.

Intermediate values for output/speed and pressure/output/kW can be established by linear extrapolation.

Feed water

• SPECK TRIPLEX Plunger Pumps are suitable for pumping clean water or 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 determine the suitability and resistance of the pumps (in standard or special versions), taking pump performance and temperature values into consideration.

Electrical

• General formula for calculating power: P (bar) x Q (l/min) = kW / 475

Mechanical / hydraulic

• Construction Characteristics:
  • Crankcase of solid sphero-cast-iron ensuring high stability and vibration dampening.
  • Crankshaft with taper roller bearings and plain bearing con rod, all running in oil.
  • Solid ceramic plunger (P62/50 has a hard metal-coated stainless steel plunger).
  • Double plunger sealing.
  • All gaskets held in seal sleeves ensuring precise centring and easy replacement.
  • Identical suction and discharge valves, easily accessible via plugs.
• Materials Used:
  • Valve Casing: Stainless steel AISI 303 (1.4305).
  • Plunger: Solid ceramic, or P62/50 stainless steel with hard metal-coating.
  • Valves: High-Grade Stainless Steel (P62/50 uses Duplex Steel / 1.4571 / AISI 316TI).
  • Sleeves: Nitrile with fabric reinforcing (P62/50 uses Aramid-Packing).
  • Crankshaft: Drop-forged and case-hardened.
• Even though SPECK-TRIPLEX P62 pumps run almost pulsation-free, a pressure accumulator may be necessary depending on the unit's construction and overall operating conditions. The same effect can also be achieved by using flexible pressure lines.

Special Versions

• The model P62/70 is available with valve casing and wetted parts of stainless steel AISI 303 and is marked with an "R" suffix.
• Special seals are available upon request.
