MILROYAL® B High Performance Diaphragm Liquid End (HPD) -Low Flow IOM Manual Manual No : 54149 Rev. : 00 Rev. Date : 10/2015 PRECAUTIONS The following precautions should be taken when working with metering pumps. Please read this section carefully prior to installation. Protective Clothing ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or near your metering pump. Additional precautions should be taken depending on the solution being pumped. Refer to Safety Data Sheets for the solution being pumped. Hearing Protection It is recommended that hearing protection be used if the pump is in an environment where the time-weighted average sound level (TWA) of 85 decibels is exceeded. (as measured on the A scale-slow response) Electrical Safety • Remove power and ensure that it remains off while maintaining pump. • DO NOT FORGET TO CONNECT THE PUMP TO EARTH. • Electric protection of the motor (Thermal protection or by means of fuses) is to correspond to the rated current indicated on the motor data plate. Liquid Compatibility Verify if the materials of construction of the wetted components of your pump are recommended for the solution (chemical) to be pumped. Pumps Water “Primed” All pumps are tested with water at the factory. If your process solution is not compatible with water, flush the Pump Head Assembly with an appropriate solution before introducing the process solution Plumbing and Electrical Connections Always adhere to your local plumbing and electrical codes. Line Depressurization To reduce the risk of chemical contact during disassembly or maintenance, the suction and discharge lines should be depressurized before servicing. Over Pressure Protection To ensure safe operation of the system it is recommended that some type of safety/pressure-relief valve be installed to protect the piping and other system components from damage due to over-pressure. Lifting This manual should be used as a guide only-Follow your company’s recommended lifting procedures. It is not intended to replace or take precedence over recommendations, policies and procedures judged as safe due to the local environment than what is contained herein. Use lifting equipment that is rated for the weight of the equipment to be lifted.

FAQs

What precautions should be followed when working with metering pumps?

Wear protective clothing, face shield, safety glasses, and gloves. Use hearing protection if the time-weighted average sound level exceeds 85 decibels.

What electrical safety steps are required?

Remove power and keep it off while maintaining the pump. Do not forget to connect the pump to earth, and ensure motor protection corresponds to the rated current on the motor data plate.

How should the liquid end be handled before introducing the process solution?

All pumps are factory tested with water. If the process solution is not compatible with water, flush the Pump Head Assembly with an appropriate solution before introducing the process liquid.
