STATEMENT OF WORK

High-Head Test Facility Pumping Unit Replacement

1. Introduction – The Bureau of Reclamation’s Hydraulics Laboratory utilizes a high-head test facility to conduct research experiments for dams and related structures and equipment. It is a unique facility that allows real-world conditions of water speed and pressure to be applied within a laboratory experiment. Existing equipment has passed its expected service life and needs to be replaced. This project involves procuring, delivering, and installing a pump, motor, and variable speed drive along with uninstalling, removing, and disposing of existing equipment.

2. Definitions –

a. CLIN: Contract Line-Item Number

b. Pumping Unit: Pump and Motor

c. TDH: Total Dynamic Head

d. VFD: Variable Frequency Drive

3. Background – The existing pump is a 7-stage vertical turbine pump, Allis-Chalmers Serial

No. 84014241T and Type 12 VTO. The existing motor is a 250 hp Allis-Chalmers Direct Current Serial No. 7-5314-32252-1-1, 3-phase (480V) with a rated speed of 1,750 rpm.

Variable speed motor control is currently conducted using a direct current drive system.

Photos and dimensions of existing equipment are shown in Section 12.

As currently operated, the pump is used infrequently and for short periods of time.

Operational flexibility, the pump’s ability to produce a wide range of values for head and flow, is the most important operating criteria to be maintained when replacing the existing pump.
