procedures.
All unauthorized personnel should be kept a safe distance from any and all work areas.
Keep hands, fingers, or tools from contacting the impeller during operation of the pump and system. Disconnect, lock and tag out
the main power source to prevent accidental start up.
Always keep face away from openings in the pump equipment. DO NOT look into hose, pump discharge or suction connections.
All auxiliary equipment such as hoses must be suitable for the chemical to be transferred. They must also be selected to safely
contain the system pressure at the operating temperature. All hose clamps must be of a material that will not be attacked by
corrosive environment or splashing of pumped liquid.
All connections should be checked for a secure liquid tight fit prior to filling and/or operating pump equipment or system.
Never turn pump on unless discharge and suction valves are open.
When connecting or wiring motor, follow all applicable electrical and safety codes.
Protect the power cable (when applicable) from sharp objects. DO NOT crimp or bind the power cable and never allow the cable to
come in contact with water, oil, grease, hot surfaces, or chemicals.
Disconnect, lock and tag out the main power source to the motor before handling the pump/motor for any reason. Lock and tag out
the switching device to prevent the unexpected application of power. FAILURE COULD RESULT IN SEVERE INJURY OR DEATH.
Avoid touching the exterior surface of the motor. It may be hot enough to be painful or cause injury.
Isolate the pump by closing suction and discharge valves prior to any maintenance. Lock and tag out the valves to prevent
accidental opening.
Do not attempt to perform any maintenance on the pump/motor unit until you are confident that the pump and its contents have been
neutralized and stabilized at ambient temperature and atmospheric pressure. FAILURE COULD RESULT IN SEVERE INJURY
OR DEATH.

OPERATING INSTRUCTIONS FOR SETHCO ZKX VERTICAL PUMPS
SETHCO
A Met -P ro Fl uid H and li ng Tec hno lo gie s Com pa ny
Thermoplastic Pumps
GENERAL DESCRIPTION
Sethco close coupled vertical pumps are centrifugal type pumping units designed for installation inside or outside of an open
tank. All pump parts in contact with the fluid are PVDF.
PRE-INSTALLATION
All Sethco pumps are tested at the factory for proper operation. Before installing your new Sethco pump, the
following is recommended:
• Determine that the equipment checks against the packing slip for completeness of order. If there is a discrepancy, please
notify Sethco immediately.
• Inspect pump and any accessories packed with the unit to assure no damage has occurred during transit.
• Determine if any packing materials are lodged in the pump.
• Turn the impeller to determine that it is not bound. Damage to the drive motor can result from an excessive load.
PUMP INSTALLATION
WARNING: WHEN HANDLING THE PUMP UNIT, IT IS VERY IMPORTANT TO PICK UP THE UNIT BY THE MOTOR AND OR
MOUNTING PANEL ONLY.
• Your vertical pump is designed for mounting inside or outside the tank by means of the mounting panel.
• Examine mounting location for maintenance accessibility.
• Secure the unit by bolting or clamping the mounting panel in place.
• The pump shaft must be vertical to avoid damage during operation.
PIPING THE PUMP
The pump has been designed with all necessary strength factors for a long, reliable service life. However, due to thermoplastic
construction, care must be taken during installation to avoid unnecessary pipe strain. If piping strains are to be encountered,
flexible connections are recommended.
• All piping must be supported independent of the pump.
• The piping should always line up naturally. Never draw the pipe to the suction or discharge connections. Piping loads
transferred to the pump body assembly can cause damage to the pump.
• Outside installations should be compensated for changes in ambient temperature. Refer to pipe manufacturers
standards for proper installation. Omission of this can result in severe strain transmitted to the pump body assembly.
• If expansion joints are used, they should be installed in a location to prevent loading of the pump connections.
• Piping should be as short and direct as possible. Avoid all unnecessary elbows, bends and fittings, as they increase
friction losses in the piping.
DISCHARGE PIPING
Installation of a valve in the discharge line, that can be used as a flow shutoff for inspection and maintenance, is recommended. It should be of a design to allow throttling or flow control. The diameter of the discharge valve should be as large or
larger than the pump discharge.
SUCTION PIPING
When the unit is mounted outside the tank, the pump inlet should be kept as short as possible, with minimum restrictions, for
easy priming and proper operation. Inlet piping should be at least as large as the pump inlet.
