PDF datasheet mirror for Speck P41 L (Speck Pumps). Verify with OEM before design.
Summary
Product Identification
The SPECK P41 series consists of high-pressure triplex plunger pumps.
Available models and their key specifications for intermittent operation are:
| Type | Code No. | Power Consump. (kW) | Pressure max. (bar) | RPM max. (min⁻¹) | Output max. (l/min) | Water Temp. max. (°C) | Plunger dia. (mm) | Stroke (mm) | Weight approx. (kg) | NPSH Required (mWs) |
|---|---|---|---|---|---|---|---|---|---|---|
| P41/33-250 | 00.1001 | 17.2 | 250 | 1450 | 33.8 | 70 | 20 | 26.0 | 31.0 | 7.5 |
| P41/48-180 | 00.1000 | 17.9 | 180 | 1450 | 48.6 | 70 | 24 | 26.0 | 31.0 | 8.5 |
| P41/51-130 | 00.0999 | 13.6 | 130 | 1100 | 51.2 | 70 | 28 | 26.0 | 31.0 | 9.0 |
| P41/58-110 | 00.0998 | 13.1 | 110 | 1100 | 58.2 | 70 | 30 | 26.0 | 31.0 | 9.0 |
| P41/70-110 | 00.6364 | 15.2 | 110 | 1100 | 67.7 | 70 | 30 | 30.0 | 31.0 | -- |
Intermediate values for output/speed and pressure/output/kW can be established by linear extrapolation.
Operating Limits
- Maximum Water Temperature: 70 °C
- Operation Type: Data provided is for intermittent operation. Data for continuous operation is available upon request.
- Safety Valve: A safety valve must be installed in accordance with guidelines for liquid spraying units. It must be set so that the admissible operating pressure is not exceeded by more than 10%.
- Warranty: Pump operation without a safety valve, or any excess in temperature or speed limits, automatically voids the warranty.
- Cavitation: Particular care must be taken when pumping warm water to ensure cavitation does not occur.
Feed Water
SPECK TRIPLEX Plunger Pumps are suitable for pumping:
- Clean water
- Other non-aggressive or abrasive media with a specific weight similar to water.
Prior to pumping any other media, suitability and resistance of the pumps (standard or special versions), considering performance and temperature values, must be checked.
Electrical
A general formula for calculating power is:
P (bar) x Q (l/min) = kW / 475
Mechanical / Hydraulic
Construction Characteristics:
- Crankcase of solid cast-iron for high stability and vibration dampening.
- Crankshaft with taper roller bearings and plain bearing con rod, all running in oil.
- Solid ceramic plunger.
- Drip-return system for long seal-life and drip-free operation.
- Identical suction and discharge valves, easily accessible via plugs.
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 SPECK-TRIPLEX P41 pumps run almost pulsation-free, a pressure accumulator may be necessary depending on the unit's construction and overall operating conditions. Flexible pressure lines can also achieve a similar effect.
- Use of a pulsation damper adds considerably to the life of seals and bearings.
Special Versions:
- 'RE' Designation: The P41/58 and P41/70 models are available in AISI 316Ti stainless steel.
- 'S' Designation: The P41/58 and P41/70 models are also available with bronze valve casings and stainless steel wetted parts.
- Special seals are available upon request.
