LUBE SYSTEMS

The pump’s fluid end is lubricated via a 24V grease system. Grease system is enclosed in fiberglass housing with a view through the front door. Grease is disturbed through an independent hose for each cylinder from the system pump. Unit is located on the driver side, ahead of the rear fender. The system is activated whenever the transmission output drive line rotation is above the preset minimum RPM.

The power end lubrication is hydraulically driven. The hydraulic pump is PTO driven off the transmission. A pump draws fluid from a 200 USG tank, mounted below and just ahead of the power end, and delivers it to the power end. A cooler is installed to prevent overheating of the oil. The flow through the cooler is controlled by a thermostatic valve allowing the oil to bypass the cooler until the minimum oil temperature is reached. They system includes the following; level sight eye, dual high flow filters (25 micron), temperature sensor (displayed on pump control data screen), pressure relief valve, pressure sensor (displayed on pump control data screen), suction line shut off valve. Nominal flow to be 50 GPM.

A drip tray is installed below the pump fluid end includes a ¾” inch drain plug located in each end.

Suction / Discharge Manifold

The suction manifold includes a 6” charge line to the pump with 6”-4” reducer and a 4” lateral off the side of the charge line. The rear of the 4” lateral line and the 4” reducer line are each fitted with a 150 LB ANSI flange located just ahead of the face of the bumper.

A 15k psi pressure transducer is mounted on the top of the fluid end.

Discharge manifold components and high pressure piping are not included.

Customer supplied components can be installed upon request.

HYDRAULIC SYSTEM

The unit’s hydraulics are powered from

(1) a wet kit mounted on a tractor (customer supplied and installed), The tractor wet kit powers the engine starter. Hydraulic connections to the tractor wet kit are made at the front of the unit at a level where and operator can reach standing on the ground. Ports in the front of the trailer are 1” female pipe. Hydraulic line connections are not provided.

(2) a PTO pad on the Caterpillar transmission, The PTO pad mounted system powers the SPM pump lube oil system

(3) a front drive installed at the harmonic balancer.

The front drive system powers the radiator cooling fan. The fan circuit is a closed loop variable speed system controlled by engine coolant temperature. It utilizes a 20 USG hydraulic oil reservoir. A secondary hydraulic oil cooler is mounted in the radiator to cool the fan drive system fluid. The fan drive fluid is filtered through a 10 micron return line filter. The tank includes the following: filler/breather cap, 2” fill port with dip stick, level sight eye, and suction line shut off valve.

ELECTRONICS

The Frac Pumpers controls and instrumentation are installed in two areas on the unit. The local control panel is mounted at chest height on the driver’s side of the unit. The local control components are housed in a weather tight stainless steel enclosure. The panel is protected from vibration with cable isolators.

The remote control panel is mounted in a suitcase style enclosure and stored on the unit in the enclosed aluminum battery box located next to the local panel. Included with the unit is 200 feet of remote cable. The cable is stored on a fixed style wrap designed to hold 200 feet of cable and mounted to the side of the local panel protective support frame.
