Speck NP10 1 160RE 2 160RE 4 140RE 7 140RE L
PDF datasheet mirror for Speck NP10 1 160RE 2 160RE 4 140RE 7 140RE L (Speck Pumps). Verify with OEM before design.
Summary
Product identification
- High-Pressure Plunger Pumps, Series NP10
- Short Stroke
- 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 in accordance with 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, making absolutely sure that cavitation cannot occur.
| Type | 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) |
|---|---|---|---|---|---|---|---|---|---|
| NP10/1-160RE | 0,5 | 160 | 1450 | 1,2 | 70 | 12 | 3,4 | 6,0 | -- |
| NP10/2-160RE | 1,0 | 160 | 1450 | 2,3 | 70 | 12 | 5,5 | 6,0 | -- |
| NP10/4-140RE | 0,9 | 140 | 1450 | 3,4 | 70 | 18 | 3,4 | 6,0 | -- |
| NP10/7-140RE | 2,0 | 140 | 1450 | 7,2 | 70 | 18 | 7,0 | 6,0 | -- |
Note on Output: The output values are calculated based on priming from a tank with the water level plane with the pump suction port. Output increases by approximately 3% where the input pressure is 1 to 4 bar. Intermediate values for output/speed and pressure/output/kW can be established by linear extrapolation.
Feed water
SPECK TRIPLEX stainless steel 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, a check must be made to find out whether these pumps are suitable, taking pump performance and temperature values into consideration.
Electrical
A general formula for calculating power is:
P (bar) x Q (l/min) = kW / 475
Mechanical / hydraulic
Construction Characteristics:
- Crankcase of solid aluminium-cast.
- Crankshaft and ball bearings together with plain bearing con rod all run in oil.
- Solid ceramic plunger.
- Double plunger sealing with leakage-return.
- All gaskets in seal sleeves ensuring precise centring and easy replacement.
- Identical suction and discharge valves, easily accessible.
Materials Used:
- Valve Casing: AISI 316
- Plunger: Solid Ceramic
- Valves: High-Grade Stainless Steel
- Sleeves: Nitrile with fabric reinforcing
- Support Rings: Teflon with graphite, run-dry-proof
- Crankshaft: Drop-forged and case-hardened
Installation Notes:
- Even though SPECK-TRIPLEX NP10 pumps run almost pulsation-free, there are cases where a pressure accumulator is necessary. This depends mainly on the construction of the unit and the operating conditions. The same effect can also be achieved by using flexible pressure lines.
- Dimension sheets are available in the official PDF.
