Technical data
2.8 Coolant type
The pump is supplied filled with Edwards coolant which is monopropylene based, and is both an antifreeze and a
corrosion inhibitor. Spare Edwards coolant is available: refer to Section 7.3. If you will use another coolant type to
replenish lost coolant:
It must prevent the formation of visible oxide sludge and scale deposits.
It must provide frost protection down to a temperature of -14 °C, when mixed in accordance with the
manufacturer’s recommendations.
It must be compatible with the materials of construction of the cooling-jacket; that is: SG iron, copper, brass
and fluoroelastomer (Viton) seals.
It must comply with the requirements of BS 6580-1992 and BS 5117.
It must be based on monopropylene glycol or ethylene glycol fluid.
It must not contain amines.
The coolants shown in Table 8 may be suitable for use in the EDP pumps. All of these coolants are amine free,
automotive grade, ethylene glycol antifreezes and must be diluted to between 35% to 50% by volume with water to
provide the required cooling protection. However, we recommend that you use Edwards coolant; Edwards cannot
guarantee that other types of coolant will provide the best corrosion protection for the pump.
