STS Series Overview

Simplex Fuel Tanks - STS Series 200 Gallon Packaged Day Tank System

The STS Packaged Design Day Tank Series represents a transformation from a build-to-order product to an inventory based product. Based upon over 50 years of experience with day tank systems, beginning with the innovation of the first packaged day tank systems in the 1960’s, Simplex has developed a new design which allows integration of over 150 options into a standard, inventory based package. Likewise, drawings have been transformed to reduce submittal lead times to days. The result is the job-specialized product that owners want with the fit and finish of a standard, high volume product.

STS Series Options

Mechanical	Option 015, Auxiliary Hand Pump, is recommended for installation on all Day Tanks equipped with motor-pumps. The hand pump is used for initial priming of the fuel line from the main tank and as a backup to the motor-pump. Option 060, 062 Fuel Strainer, is recommended whenever there is a possibility of fuel contamination. Day Tank pumps have extremely close tolerances. Fine abrasives in suspension degrade pumping ability and can jam pump. In order to assure maintenance of pump prime, one of the following options is recommended for installation on all Day Tanks equipped with motor-pumps: Option 070: Check valve; Option 080, 083: Solenoid valve; or Option 090: Foot valve. OPT - Description 015 - Auxiliary hand pump, 20 gallons per 100 strokes, 1" NPT (Side mounted) 025 - Locking manual fuel fill cap 060 - Fuel strainer 062 - Duplex strainer 063 - Vent cap 064 - Emergency vent 065 - Drain hand valve 070 - Check valve 080 - Solenoid valve 083 - DC Solenoid Valve 087 - Manual fuel shut-off valve, bronze 088 - Manual fuel shut-off valve, fire-rated 090 - Foot valve 093 - Fusible link valve 095 - Pressure relief valve 100 - Pressure gauge 101 - Vacuum gauge 103 - Flow gauge in line with pump, to 29 GPM 104 - Ball motion flow indicator 105 - Temperature gauge 120 - Extra 1" pipe connection 125 - Extra drop tube 130 - Oversize pipe connections, 1 1/4" to 2 1/2" NPT 131 - Oversize pipe connections, 3” to 6” NPT 140 - Special paint colors 180 - Weatherproof modification 192 - Containment drain hand valve

Duplex Pump Systems	Duplex pump options are used to increase the reliability of a day tank system through the addition of a second, backup pump and level control. In a duplex system, one pump is designated the “lead” pump and the other is the “lag” pump. The lead pump automatically refills the day tank over the tank’s normal operating range of 50% to full. Normally, once the tank has been initially filled, the fuel level should never drop below 50%. Less than 50% is indicative of either a failure of the lead pump or consumption in excess of pump capacity. The lag pump and its separate level controller, acting as a backup senses a drop in fuel level below 50% and starts the lag pump, which then continues to run, along with the lead pump, until the tank is full. When ordering, remember that duplex systems include two motor-pumps and therefore require a quantity of two of any option related to the motor or pump, such as solenoid valves, strainers, etc. OPT - Description 345 - Duplex pump controller 346 - Two running time meters 349 - Basic PLC based level and duplex pump controller (replaces analog controller)
