Speck P71 145 180R 200 130R 250 100R L
PDF datasheet mirror for Speck P71 145 180R 200 130R 250 100R L (Speck Pumps). Verify with OEM before design.
Summary
Product identification
- High-Pressure Plunger Pumps, Series P71
- Low Pressure / Stainless Steel construction
Operating limits
Data provided is for intermittent operation; data for continuous operation is available on request.
A safety valve must be installed according to 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, or any excess in temperature or speed limits, automatically voids the warranty.
Particular care is required when pumping warm water to prevent cavitation.
Performance Data (Intermittent Operation)
| 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) |
|---|---|---|---|---|---|---|---|---|---|---|
| P71/145-180R | 00.4435 | 51.5 | 180 | 700 | 145.2 | 60 | 42 | 52 | 215 | 9.7 |
| P71/200-130R | 00.4436 | 52.7 | 130 | 700 | 205.8 | 60 | 50 | 52 | 215 | 9.7 |
| P71/250-100R | 00.4437 | 49.0 | 100 | 700 | 249.1 | 60 | 55 | 52 | 215 | 8.5 |
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 in stainless steel 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, suitability and resistance of the pumps (standard or special design), considering performance and temperature values, must be checked.
Mechanical / hydraulic
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.
- Double plunger sealing.
- All gaskets in seal sleeves ensuring precise centring and easy replacement.
- Suction and discharge valves easily accessible via divided valve casing.
Materials Used
- Valve Casing: Stainless steel AISI 303
- Plunger: Solid ceramic
- Valves: High-Grade Stainless Steel
- Sleeves: Nitrile with fabric reinforcing
- Crankshaft: Drop-forged and case-hardened
Even though SPECK-TRIPLEX P71 pumps run almost pulsation-free, a pressure accumulator may be necessary depending on the unit's construction and operating conditions. Flexible pressure lines can achieve a similar effect.
