C6000 Series screw pumps are designed principally to handle clean lubricating liquids within the viscosity range of 33 to 14,000 SSU and temperatures up to 250°F. Their main use is in the wide variety of process applications found in pumping lubricating oils, fuel oils and their derivatives such as additives, grease and bitumen / asphalt.
Description
Plenty Mirrlees have extended the range and versatility of the C6000 series triple screw pump to offer more flow selections, higher pressure capability, more configurations and additional mounting options. The type 7 insert has been re-designed to form a pump in its own right, without the need for an additional casing, primarily for direct machine mounting and tank top versions. The type 7 insert retains dimensional interchangeability with its predecessors, the types 5 and 6 in respect of the critical dimensions for mounting in new and already installed C6000 series pump casings.
The type 7 offers a much improved and extended range yet retains all the interchangeability required for servicing the existing pump population.
Cast iron casings have been upgraded to Ductile iron (SG iron) to improve the reliability and integrity of these critical pressure containing components. This upgrade improves the acceptability of the product of oil industry installations.
Short lead (SL) screwsets have been introduced as an alternative pitch to the existing screwsets, known as normal lead (NL). This option effectively provides two alternative flow rates for each insert frame size, doubling the number of pumps available in the range.
