These questions and answers are specific to Line Item 0016, One (1) Heavy Duty Slurry Pump, Eddy Pump 4 inch.

For additional reference, 2 pictures are included as attachments which shows where the scaffolding is to be set.

Question 1. What type of material is being pumped and for what process?

Answer: The pump will be used to remove debris from the bottom of a 60’ deep pump well. Materials to be removed are submerged mud, sand, rocks, and large wood splinters.

Question 2. Desired flow (GPM,M3/HR, YD3/HR)?

Answer: (250 gpm minimum?)

Question 3. What are the slurry specs (specific gravity, viscosity, pH, temperature)? ____sg, _____cp, _____pH, _____°F

Answer: The material is not a consistent slurry; it is a mixture of river bottom debris.

Water temperature will be around 40 degrees F.

Question 4. Percentage of solids? _____%

Answer: The percentage of solids will vary as the debris is pumped.

Question 5. Is the material abrasive (No/Yes - low, med, high)?

Answer: Rocks will be abrasive.

Question 6. Max solid size to pass through the pump?

Answer: Up to 3” diameter

Question 7. Material Construction of existing pipeline and the inner diameter?

Answer: 5” heavy duty polyurethane will be rented along with pump

Question 8. Will this be a flooded suction (gravity fed), submersible (excavator attachment, cable deployed from a crane, vertical on suction stand/rail system) or self-priming pump application?

Answer: Submersible

Question 9. How will the pump be powered (electric, hydraulic, or direct-drive diesel)?

Answer: Electric

Question 10. If Hydraulic, do you request to be quoted the appropriate size hydraulic power unit? (Yes/No)

Answer: N/A

Question 11. If Electric, what are your power requirements (Voltage, Phase, Hertz) and will a VFD (Variable Frequency Drive) be required to control the speed of the motor (efficiency control)? (Yes/No)

Answer: 460-480 volts, three phase, 60 hertz. Yes, a VFD will be required.
