Datasheet summary
Speck P22 L
PDF datasheet mirror for Speck P22 L (Speck Pumps). Verify with OEM before design.
Summary
Product identification
SPECK TRIPLEX High-Pressure Plunger Pumps, Series P22.
Available models include:
- P22/15-280
- P22/21-240
- P22/28-100
- P22/28-130
Operating limits
Performance data 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 cannot be exceeded by more than 10%. Exceeding temperature or speed limits, or operating without a safety valve, voids the warranty.
Particular care must be taken when pumping warm water to ensure cavitation does not occur.
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) |
|---|---|---|---|---|---|---|---|---|---|---|
| P22/15-280 | 00.3750 | 8,6 | 280 | 1450 | 15,1 | 60 | 16 | 18 | 9,6 | 7,0 |
| P22/21-240 | 00.5788 | 9,0 | 240 | 1450 | 19,0 | 60 | 18 | 18 | 9,6 | -- |
| P22/28-100 | 00.3449 | 5,8 | 100 | 1450 | 28,3 | 70 | 22 | 18 | 9,6 | 6,5 |
| P22/28-130 | 00.4767 | 7,5 | 130 | 1450 | 28,3 | 70 | 22 | 18 | 9,6 | 6,5 |
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 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.
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
Electrical
A general formula for calculating power is: P (bar) x Q (l/min) = kW / 475
Mechanical / hydraulic
Construction Characteristics
- Crankcase of aluminium-cast.
- Crankshaft with cylinder roller bearing (grooved ball bearing on P22/28-100) and plain bearing con rod, all running in oil.
- Solid ceramic plunger.
- Drip-return ensuring long seal-life and drip-free operation.
- Identical suction and discharge valves.
Even though SPECK-TRIPLEX P22 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. A pulsation damper adds considerably to the life of seals and bearings.
