2.10 Coolant
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. A Material Safety Data Sheet for the
coolant is available on request.
If using another coolant type to replenish lost coolant:
z It must prevent the formation of visible oxide sludge and scale deposits.
z It must provide frost protection down to a temperature of -14 °C (7 °F), when mixed in accordance with the
manufacturer’s recommendations.
z It must be compatible with the materials of construction of the cooling system; that is: SG iron, copper,
brass, aluminium, stainless steel, rubber (hoses) and fluoroelastomer (Viton) seals.
z It must comply with the requirements of BS 6580-1992 and BS 5117.
z It must be based on monopropylene glycol or ethylene glycol fluid.
z It must not contain amines.
The coolants shown in Table 10 may be suitable for use in the CDX and IDX 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, Edwards recommends the use of Edwards coolant; Edwards
cannot guarantee other types of coolant will provide the best corrosion protection for the pump.
