Speck P45 37 400 L

Summary

Product identification

• Series: P45 High-Pressure Plunger Pumps
• Type: P45/37-400
• Code No.: 00.5975

Operating limits

Data are for intermittent operation; data for continuous operation are available on request.

• Power Consumption: 30,2 kW
• Pressure max.: 400 bar
• RPM max.: 1000 min⁻¹
• Output max.: 37,0 l/min
• Water-Temp. max.: 40 °C
• NPSH Required: 7,6 mWs

Intermediate values for output/speed and pressure/output/kW can be established by linear extrapolation. A general formula for calculating power is: P (bar) x Q (l/min) = kW / 475.

Feed water

SPECK TRIPLEX Plunger Pumps are 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.

Particular care must be taken when pumping warm water, ensuring that cavitation cannot occur.

Mechanical / hydraulic

• Plunger dia.: 20 mm
• Stroke: 42 mm
• Weight approx.: 58,0 kg

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: Special Brass.
• Plunger: Solid ceramic.
• Valves: High-Grade Stainless Steel.
• Sleeves: Nitrile with fabric reinforcing.
• Crankshaft: Drop-forged and case-hardened.

Installation and Safety

Even though SPECK-TRIPLEX P45 pumps run almost pulsation-free, a pressure accumulator may be necessary depending on the unit's construction and operating conditions. The same effect can also be achieved by using flexible pressure lines.

A safety valve must be installed in accordance with the guidelines for liquid spraying units, set so that the admissible operating pressure cannot be exceeded by more than 10%. Pump operation without a safety valve, as well as any excess in temperature or speed limits, automatically voids the warranty.
