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 a wide range of 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. A pump curve recently measured on the original pump is shown in Section 11, along with photos and dimensions of existing equipment.

Operational flexibility is the most important factor in providing a new pumping unit. It is recognized that the specified range of head and flow is wide and pushes the envelope of what is available. Pump efficiency is not an important consideration in this case as the unit will be used infrequently and for short periods of time. Typical operations are no more than 8 hours per day for only 10 weeks each year, approximately.
