North Ridge PHS Series Triple Screw pump

PHS Series Triple Screw pump Flow RateUp to 10.2m³/hrHead (Pressure)Up to 16 barInlet/Outlet Sizes1" to 1 1/2"Operating TemperatureUp to 150°CViscosity1.2 to 5000cpDrive OptionsElectric Motor, Magnetic Drive The PHS series of triple screw pump is mainly designed for transfer, separator, circulating and lubricating applications; this is due to the fact it can produce low flow rates up to 10.2m³/hr at medium pressures up to 16 bar. It can handle various fuel oils and lubricating oils not containing solids, ranging in viscosity from 1.2 to 5000cp. The compact design of this pump coupled with the suction and delivery ports mounted on top of the pump makes it excellent for applications with space limitations. It can also be mounted horizontally and vertically depending on customer's preference. Our screw pumps have numerous benefits over other positive displacement pumps such as gear pumps. They produce low noise levels, are compact as no gearbox is required, produce low pulsations, are excellent at self-priming and can handle fluids containing trapped air. This self-priming screw pump range is fitted with a maintenance free ball bearing and can be fitted with a built-in relief valve for protecting the system from overpressure. This range is supplied with mechanical seal as standard but can be fitted with a magnetic coupling if required. The magnetic drive enables a completely maintenance and leak free solution for applications where this is a concern. The PHS series can be fitted with an Atex motor for installation in non-safe areas. It is marine type approved by ABS, BV and RINA and can be marine witness tested by various classification bodies if required. The PHS series of triple screw pump is manufactured in ductile cast iron (GGG40) as standard and can be utilised for various applications within the marine and industrial markets. Some of the fuels and oils this range can handle include diesel (DO), Marine diesel oil (MDO), Low sulphur marine gas oil (LSMGO), Heavy fuel oil (HFO), lube oil and many more. Common applications include fuel transfer, lube oil transfer, lubricating oil circulation, fuel booster, fuel oil separator, gear box lubrication, thruster lubrication and engine lubrication.
