The user must take responsibility in the selection of the products materials of construction. Empire 
Pumps Ltd will act in an advisory role and offer recommendations; however, the user is liable for the 
product selection in line with solutions and temperatures in which the equipment is operated.   
 

Safety Precautions

 

 
WARNING: Prior to operating the pump read and understand the operating and maintenance 
instructions.  

WARNING: Ensure the pump is compatible with the fluids and temperatures being transferred. Always 
consult Empire Pumps Ltd if there is any change in chemical concentrations or solution temperatures.  

WARNING: Wear protective eye and personal equipment at all times when operating the pump. Follow 
standard safety procedures when handling corrosive or harmful solutions. 

WARNING: Ensure all operators of this equipment have been trained for safe working practices, 
understand its limitations and wear safety goggles and equipment at all times.  

WARNING: Correct procedures must be followed to drain the pump of all chemistries prior to physical 
inspection of the pump.  

WARNING: Excessive Pressure. Can result in serious injury or equipment damage. Do not service or 
clean the pump whilst the system is pressurised. Relieve pressure from the system prior to 
disassembly.  

WARNING: Never operate the pump above the specified maximum operating pressure of the pump.  

WARNING: Suction and discharge connections must be compatible with the solutions being pumped 
and the maximum pressure capability of the pump.  

WARNING: Maximum temperatures are based on mechanical stress only. Certain chemicals will 
significantly reduce the maximum operating temperature of the pump materials. Consult with the 
chemical manufacturer and Empire Pumps Ltd for solution compatibility and temperature limitations.   

WARNING: The pump must not be used as structural support to the piping system. Ensure suction and 
discharge pipe-work are independently supported to avoid stress on the pump parts.  

WARNING: Use only Empire Pumps Ltd genuine spare parts to assure compatible pressure rating and 
longest service life.  

WARNING: Re-torque all fasteners before operation. Excessive torque is unnecessary and may cause 
damage to the pump.  

WARNING: Upon receipt of the pump, inspect for any signs of shipping damage. If damage has 
occurred contact Empire Pumps Ltd.
