Speck P51 135 90Bz L
PDF datasheet mirror for Speck P51 135 90Bz L (Speck Pumps). Verify with OEM before design.
Summary
Product identification
The SPECK P51 series consists of high-pressure plunger pumps.
Models covered:
- P51/135-90 (Code No. 00.5088)
- P51/135-90Bz (Code No. 00.4448)
Operating limits
- Data provided is for intermittent operation; data for continuous operation is available on request.
- Intermediate values for output/speed and pressure/output/kW can be established by linear extrapolation.
| Parameter | Value | Unit |
|---|---|---|
| Power Consumption | 23,8 | kW |
| Pressure, max | 90 | bar |
| RPM, max | 800 | min⁻¹ |
| Output, max | 134,1 | l/min |
| Water Temperature, max | 60 | °C |
| NPSH Required | 7,8 | mWs |
A safety valve must be installed to ensure the operating pressure is not exceeded by more than 10%. Exceeding temperature or speed limits, or operating without a safety valve, voids the warranty. Cavitation must be avoided, especially when pumping warm water.
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), considering performance and temperature values, must be checked.
Mechanical / hydraulic
- Plunger diameter: 42 mm
- Stroke: 42 mm
- Weight (approx.): 60,0 kg
Construction Characteristics:
- Crankcase of solid spheroidal-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.
- Double plunger sealing.
- Drip-return system for long seal-life and drip-free operation.
- All gaskets held in seal sleeves for precise centring and easy replacement.
- Identical suction and discharge valves, easily accessible via plugs.
Materials Used:
- Valve Casing: Special Brass (P51/135), Bronze (P51/135 Bz)
- Plunger: Solid ceramic
- Valves: High-Grade Stainless Steel
- Sleeves: Nitrile with fabric reinforcing
- Crankshaft: Drop-forged and case-hardened
General Power Calculation Formula: P (bar) x Q (l/min) = kW / 475
Special Versions
- P51/135 'RE': Available with valve casing and wetted parts of AISI 316Ti stainless steel.
- P51/135 'S': Available with bronze valve casing and stainless steel wetted parts.
