PDF datasheet mirror for Speck P21 16 200 15 160 18 130 23 130 L (Speck Pumps). Verify with OEM before design.
Summary
Product identification
The P21 series consists of high-pressure plunger pumps. Available models:
- P21/15-160
- P21/16-200
- P21/18-130
- P21/23-130
Operating limits
Performance data are for intermittent operation; data for continuous operation are available on request. 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
| 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) |
|---|---|---|---|---|---|---|---|---|---|---|
| P21/15-160 | 00.0543 | 4,6 | 160 | 1420 | 14,7 | 70 | 18,0 | 14,1 | 8,5 | 5,5 |
| P21/16-200 | 00.0866 | 5,9 | 200 | 1450 | 15,1 | 70 | 16,0 | 18,0 | 8,5 | 7,0 |
| P21/18-130 | 00.0555 | 4,6 | 130 | 1420 | 18,1 | 70 | 20,0 | 14,1 | 8,5 | 6,0 |
| P21/23-130 | 00.0579 | 5,9 | 130 | 1420 | 23,1 | 70 | 20,0 | 18,0 | 8,5 | 7,4 |
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 versions) must be checked, considering performance and temperature values.
Particular care must be taken when pumping warm water, making absolutely sure that cavitation cannot occur.
Mechanical / hydraulic
Construction Characteristics:
- Crankcase of aluminium-cast.
- Crankshaft and taper roller bearings together with plain bearing con rod all run in oil.
- Solid ceramic plunger.
- Drip-return ensuring long seal-life and drip-free operation.
- 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 Considerations: Even though SPECK-TRIPLEX P21 pumps run almost pulsation-free, there are cases where a pressure accumulator is necessary. This will depend mainly on the construction of the unit and the conditions under which it is operated. The same effect can also be achieved by using flexible pressure lines. In any case, use of a pulsation damper adds considerably to the life of the seals and bearings.
Safety Rules: A safety valve is to be installed in accordance with the guidelines for liquid spraying units 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.
Special Versions:
- The P21/15, /18, /23 models are available in AISI 316Ti stainless steel under the supplement letters ‘RE’.
- The P21/15, /18, /23 models are also available with bronze valve casings and stainless steel wetted parts under the supplement letter 'S'.
- Special seals are available upon request.
