For almost 30 years, pdblowers has worked with Ernst Concrete, providing positive displacement blower packages and accessories utilized in concrete plant conveying systems. The two most recent pressure packages are used for bulk tanker unloading; the blower systems move the cement out of the tanker trucks and into the cement silos at the plant.
These two packages feature the following components:
- 406 RAM Blower
- Electric Motor, 40 HP, 1800 RPM, TEFC, SF: 1.15, 230-460/3/60
- Motor Slide Base w/ Twin Adjusting Screws
- VB567 Baseplate w/ Guard
- 40 HP V-Belt Drive
- Inlet Filter, 4″, Paper Element
- Inlet Silencer, 4″, Chamber-Absorptive
- Inlet Morse Coupling, 4″
- Discharge Flexible Connector, 4″
- Discharge Silencer, 4″, Chamber-Absorptive
- Pressure Relief Valve, 2″, Set at 14 PSIG
- Pressure Gauge, 2.5″, 0-15 PSI, Snubber and Gauge-cock
- Discharge Check Valve, 4″, EPDM Seat
Performance conditions:
- Inlet Volume: 400 ACFM / 346 SCFM
- Inlet Temperature: 100 F
- Inlet Pressure Drop: 0.3 PSIG
- Blower Inlet Pressure: 14.1 PSIA
- Discharge Pressure Drop: 0.2 PSIG
- System Discharge Pressure: 13.0 PSIG
