Speck NP30 90 150 100 120 L

Summary

Product identification

The SPECK NP30 series are high-pressure plunger pumps.

Available models:

• NP30/90-150 (Code No. 00.7016)
• NP30/100-120 (Code No. 00.6917)

Operating limits

Performance data 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.

NP30/90-150

• Power Consumption: 26.3 kW
• Pressure max.: 150 bar
• RPM max.: 1450 min⁻¹
• Output max.: 86.0 l/min
• Water Temp. max.: 40 °C
• NPSH Required: 8.2 mWs

NP30/100-120

• Power Consumption: 23.6 kW
• Pressure max.: 120 bar
• RPM max.: 1450 min⁻¹
• Output max.: 100.0 l/min
• Water Temp. max.: 40 °C
• NPSH Required: 8.2 mWs

General Operating Notes

• A safety valve must be installed in accordance with guidelines for liquid spraying units, set so 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.
• Even though SPECK-TRIPLEX 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 the same effect.

Feed water

SPECK TRIPLEX Plunger Pumps are suitable for pumping clean water and other non-aggressive or non-abrasive media with a specific weight similar to water.

• Prior to pumping any other media, a check must be made to establish whether standard and/or special-version pumps are suitable, considering pump performance and temperature values.
• Particular care must be taken when pumping warm water, ensuring that cavitation cannot occur.

Electrical

A general formula for calculating power is: kW = (P (bar) x Q (l/min)) / 475

Mechanical / hydraulic
