What is OH2 pump?
The pump type HZC ( OH2 ) is a series of horizontal overhung centerline mounted, single stage, single suction heavy duty centrifugal pumps with diffuser and volute design casings.
What is an OH1 pump?
General. Our basic API 610 type OH1 pumps are foot mounted, single stage, overhung pumps with a single bearing housing. The pump and motor are flexibly coupled and installed on a common baseplate. The coupling design allow removal of the back pull-out assembly without disturbing the driver, coupling hubs or casing.
What is the pump theory?
Pumps are an integral part of many pressure systems. Pumps add energy, or head gains, to the flow to counteract headlosses and hydraulic grade differences within the system. A pump is defined by its characteristic curve, which relates the pump head, or the head added to the system, to the flow rate.
What is between bearing pump?
A between bearings centrifugal pump uses one or several impellers installed on a shaft that is suspended at both ends between two bearings. An overhung centrifugal pump uses one impeller installed on a shaft that is suspended at one end by bearings.
What is an overhung pump?
Overhung Impeller Type: The impeller is mounted on the end of a shaft which is “overhung” from its bearing supports. – Close Coupled pumps where the impeller is mounted directly on the motor shaft – Separately coupled or frame mounted where the impeller is mounted on a separate pump shaft supported by its own bearings.
What is difference between OH & BB pump?
OH – Overhung pumps – The impellers of these pumps protrude from the bearings. The impellers of these pumps can be mounted either horizontally or vertically. BB – Between bearing pumps – The impellers of BB pumps are suspended in between the supports.
What is the working principle of water pump?
The working principle of a water pump mainly depends upon the positive displacement principle as well as kinetic energy to push the water. These pumps use AC power otherwise DC power for energizing the motor of the water pump whereas others can be energized other kinds of drivers like gasoline engines otherwise diesel.
What is VS type pump?
BB – Between bearing pumps – The impellers of BB pumps are suspended in between the supports. For all pumps of this type, the impeller is placed horizontally, in plane with the bearings. VS – Vertically suspended pumps – VS pumps are supported above the medium to be pumped.
What kind of pump is an OH2 pump?
OH2 Type Pump This type of pump is centerline supported. You can see that there is no leg support at the bearing end as compared to OH1 type in the image below. It is also single stage end suction pump with single bearing housing.
What kind of pump is Amarinth OH2 a series?
A range of API 610 OH2 single stage, centreline mounted centrifugal end suction pumps with centreline discharge manufactured in a variety of alloys. Amarinth A Series pumps are available in a variety of materials as standard which include the following pump / impeller combinations.
Can a OH2 pump be fitted with a baseplate?
A ‘space saving’ reduced footprint baseplate is also available for use where space is at a premium. The OH2 Pumps can be fitted with a variety of proprietary components (i.e. seals, motors and couplings) from all the major manufacturers to cater for customers site preferences.
What is the difference between API oh1 and OH2?
The API OH1 is a horizontal, foot mounted, single stage, overhung pump with end suction. The pump is mounted to a baseplate and driven via a flexible coupler. The API OH2 is a horizontal, centerline mounted, single stage, overhung pump with end suction and a single bearing housing.
