Dewatering Trash Pumps

22-MAR-2019

1. DESCRIPTION OF ITEMS TO BE PROCURED:

a. General Description:

The contractor shall furnish two (2) 12-inch dewatering pump systems. Each system shall include: one (1) 12” submersible trash pump head; one (1) trailer mounted hydraulic power unit with Tier IV diesel engine; one (1) hydraulic line set 50’ in length with quick connect fittings; and one (1) set of discharge piping as described below. The pump systems will be used to dewater navigation locks throughout the state of Florida. The locks are fresh, brackish, and saltwater depending upon location. The maximum vertical discharge height from the bottom of the structures to the top of the lock gates is 32’.

b. Characteristics of these Items:

Each pump head, power unit, and line set shall be trailer mounted for transportation. The mounting trailers shall be DOT (Department of Transportation) approved with diamond plate fenders, cushioned suspensions, pintle hitches, tow crossbars, stabilizing jacks, and hydraulic brakes. The pump engines shall at least be 4-cylinder, water-cooled, and Tier IV diesel powered with a fuel capacity sufficient to provide a minimum operating time of 30-hours at full load. Standard pump equipment shall include, but not be limited to, lifting ball provisions, locking provisions for battery and fuel cap, integral fuel tank cleanouts and drain ports, suction strainers, and fuel and vacuum gauges.

The pumps, at minimum, shall have inlet and outlet diameters of 12”. Hydraulic hose lengths for the pumps, in and out of the units, shall be at least 50’ in length.

Pump Characteristics at 68oF, 1 atmosphere pressure, and fresh water S.G. of 1.00

Pump Size 12” Performance (minimum) 4,000 GPM @ 35’ TDH

Engine Tier IV 4-cylinder water-cooled Fuel Type Diesel

Trailer Mounted (Y/N) Y Inlet/Outlet Hydraulic Hose Length

(minimum) 50’

Solids Handling (minimum diameter) 3” Discharge Horizontal or Vertical

The discharge piping set shall be made of various lengths of flanged pipe to accommodate different vertical lift and horizontal discharge configurations at each of the structures. Short straight pipe sections shall have a minimum length not less than 4’ and not more than 6’. Long straight pipe sections shall have a minimum length not less than 8’ and not more than 12’. The total length of straight piping for each system will be no less than 50’. For each pump system, at least one 90-degree elbow is required to transition from the vertical lift to a horizontal discharge. For each system with a horizontal pump head discharge a 90-degree elbow is required to transition to vertical lift.

Sufficient assembly hardware and gasket material will be supplied to assemble all sections of discharge piping. See typical dewatering configuration in Figure 1 below.

The hydraulic power units will be positioned either on land at the edge of the lock structure, or on a barge immediately up/downstream of the lock structure.
