ASTM F2798-09(2014)e1

Standard Specification for Sealless Lube Oil Pump with Oil Through Motor for Marine Applications

SCOPE
1.1 This specification defines the requirements applicable to design, construction and testing of sealless, rotary positive displacement pumps with oil-through motors for ship lubricating oil service. The complete pump and motor assembly is referred to as canned lube oil pump (CLP). This specification applies to CLPs pumping oil with a SAE rating of 20–50.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3.1 Definitions of Terms Specific to This Standard:
3.2 canned lube oil pump unit—a unit, which when assembled as a pump and motor, is completely sealed from leakage to the
environment. Lubrication and cooling of motor bearings and primary cooling of motor windings and insulation are achieved by
circulating a portion of the fluid being pumped (oil) through the motor.
3.3 capacity—the quantity of fluid actually delivered per unit of time at the rated speed, including both the liquid and dissolved
or entrained gases, under stated operating conditions. In the absence of any gas or vapor entering or forming within the pump, the
capacity is equal to the volume displaced per unit of time, less slip, motor bearing lubrication and motor cooling flows.
3.4 displacement—the volume of fluid displaced per revolution of the rotor(s).
3.5 rated condition point—the required capacity at speed, pressure, viscosity and power as specified by the purchaser.
3.6 slip—the quantity of fluid that leaks through internal clearances of a pump per unit of time.
4. Classification
4.1 Pumps will be classified as follows:
4.1.1 Type II—Screws with timing gearsgears.
4.1.2 Type III—Screws without timing gearsgears.
4.1.3 Type X—Vane (sliding)(sliding).
4.1.4 Type XI—Sliding shoeshoe.
4.2 Motor Types: Types—Oil-through type that uses the oil to cool the motor and lubricate the bearings.

5.1.5 Capacity in gallons per minute or litres per minute at rated discharge pressure at specified operating condition.
5.1.6 Discharge pressure in pound-force per square inch gauge (psig) or kilopascal (kPa) gauge at specified operating condition.
5.1.7 Inlet pressure conditions (NPIPA)(NPIPA).
5.1.8 Oil Viscosity and temperature for minimum and maximum operating conditions.

7.4 At normal operating conditions, the airborne noise level of the pump shall not exceed 85 dBA.
7.5 CLPs shall be designed such that no damage will result from reverse rotations of at least a one-minute duration with no
restriction in flow of oil to or from the CLP.
7.6 Unless otherwise specified, vertical CLPs shall be assembled with the conduit box mounted over the pump outlet flange.
Conduit box cable entrance shall be oriented downward, unless otherwise specified. Horizontal pumps shall specify orientation of
conduit box.
7.7 The connection between the motor shaft and the pump rotor shall be splined or consist of a rigid connection.
7.8 To facilitate and maintain alignment, the motor bracket to pump joint shall be rabbetted.
7.9 Motor bracket to pump joint shall be o-ring sealed.
7.10 Direction of rotation shall be indicated by an arrow cast into the pump or by a label plate attached to the CLP.
7.11 An internal or separate relief valve is not required to be provided with the CLP.
8. Pump Design
8.1 Pump inlet and outlet connections shall be flanged. Pump flanges shall mate to ASME/ANSI B16.5 pipe flanges. Cast iron
and non-ferrous material case flanges shall be flat face, unless otherwise stated in the ordering data. Flanged connections shall meet
the external forces and moments requirements in API Standard 676. Spool piece adapters (threaded and seal-welded, or O-ring
sealed to the pump case on one end and flanged on the other end) may be furnished to meet the flanged inlet and outlet requirement.
8.2 Pumps of capacity 100 gpm and greater shall be equipped with vent, drain, inlet, and outlet gage connections. Where
threaded connections are used they shall be straight thread with O-ring seal. Tapered pipe thread connections are prohibited. Small
capacity pumps (under 100 gpm) do not require vent, drain, and gage connections.
8.3 Pumps shall be designed to counteract radial and axial thrust loads encountered during operation.
8.4 Pumps shall be self-priming and capable of removing air from the suction lines.
8.5 Pumps shall be designed to handle up to 8 % entrained air.
9. Motor Design
9.1 Motors may be single speed, two-speed or single speed with a variable speed drive to support pump operation at various
temperatures and viscosities. Single speed motors shall be sized for the maximum flow at the system relief valve cracking pressure
at maximum viscosity. If a two speed motor is specified, rating of the low speed winding shall be based on power required at the
low speed with maximum viscosity oil during cold startup. The high speed winding rating shall be based on power required at
pump rated conditions. Motors driven by variable speed drive units should be sized so that the motor can support pump cold
start-up operation and normal rated condition operation without overloading the motor.
