Pitbull Models S3C & S3S
3” Submersible Pumps
The models S3C (steel) and S3S (316 SS) are capable of pumping a wide variety of debris, solids and sludges, solvents and chemicals. Outfitted with CIPC full port check valves these 3” units can pump a full 3” diameter solid, and at a low flows/high heads. This makes the model S3 a true ‘trash-handling’ pump in a small, cost effective package.
The AP200 pneumatic panel is supplied standard with the pump and is fully automatic; no level controls are required.
Applications for these pumps are almost limitless. Chip/coolant sumps, coal handling/ash sumps, boiler rooms, packing plant water, raw sewage, old/water separators, battery sludge, tank farm sumps, slop oil; the list of excellent applications is extensive.
They are also available with suction capabilities to help pull in viscous or bridging solids (great for cleaning sumps with heavy, settled solids.) *See ‘Transfer/Self-priming’ pumps for dry piped applications requiring suction lift.

Model and Options Selection:
Part Number Ø S3 __/ __/ __
Standard units:
#S3C = a steel submersible pump with steel checks and nitrile seats.
#S3S = a 316SS submersible pump with 316SS checks and nitrile seats
Optional examples:
#S3C/U/FI =a steel submersible pump with urethane seats and flow inducement option.
#S3S/V = a 316SS submersible pump with viton seats.
A complete pump contains: pump, inlet and discharge check valves, an AP200 control panel and 15’ of nitrile/polyester braided airlines (3)
Description of options:
‘FI’ flow inducement. This is an air powered, vacuum generator mounted to the exhaust valve of the control panel. It is operated by a manual ball valve: ‘open’ generates full suction force; with the valve ‘closed’ the pump runs as a standard, gravity fed unit
Valve seat selection:
Nitrile -Good all-purpose elastomer. Medium chemical, oil and solvent resistance, good strength, use to 170°F.
Viton -Excellent resistance to oxidizers and solvents. Medium strength, use to 250°F.
Teflon -Best chemical resistance of all. Inert to acids, bases and solvents. Lower cycle life, non-elastomeric, use to 300°F.
Urethane -Best resistance to abrasion. Toughest of the elastomers, with mild chemical resistance, use to 150°F.
EDPM -Good head and acid/base resistance.
Tougher than viton but poor solvent resistance, use to 300°F.

AP200 Control Panel
Commonly Asked Installation/Application Questions
How much air will it actually use?
The Pitbull matches your incoming flow rate. So when the inflow drops to
half, the air consumption is cut in half too. Actual air consumption is usually much less than shown unless inflow is constant.
Where is the control panel mounted?
Place within 15’ radius of the airlines, above the pump. Up to 20’ extra lines can be ordered (consult CIPC if more is required).
Can the airlines be hard-piped?
Yes they can, but the ID’s of our standard lines must be matched.
Can the piping be reduced?
Smaller piping causes higher head and velocity, and the pump may pass things the piping can’t. Try to avoid dropping more than one pipe size.
