Goulds & Berkeley Pump installation: Tips and best practices

Goulds Pump placement

  • Ensure it stays on a flat surface. This helps the load.
  • The unit placement must help avoid any distorting forces.
  • Enough space should also be a consideration for operation and maintenance

General pipe guidelines

Diameter and length selection of suction, pressure pipes with other components must be considered. The operating pressure should not exceed the maximum permissible values. The power rating of the drive system installed must be sufficient. NPSH chart is available upon request.

The diameter pipe must be equal to or greater than the size of the connection on the Goulds pump.

If possible, the transition between the various diameters of the pipe should be made with a transition angle of approx. 8 degrees.

Pipe alignment is essential for pump connections.

It should be possible to connect a pipe and Goulds pump flanges without placing one part under pressure.

Support the pipe directly in front of the Goulds pump. The pump may not support heavy pipes and fittings.

Install the Apollo shut-off valve on the suction and pressure pipe as close as possible to the connection flanges to allow isolation of the Goulds pump for maintenance and repair. Shut-off valve must be of a type that will enable the flow of straight lines, such as Apollo gate or globe valves. 

Internal diameter alignment must exist between the shut-off valve and pipe. If there is a possibility that backflow of liquid can cause the Goulds pump to turn in the opposite direction when it stops, the non-return valve should be placed in the pipe to prevent it.

Install the instrument in the pipeline for monitoring during surgery.

If applicable, connect the pump unit to the appropriate security system. Protector shields the heat pipe.

Specific regulations related to suction and pressure pipes.

Cleaning all parts in contact with the fluid is essential. 

Note: When pumping viscous fluids, there can be a significant loss of pressure in the suction and pressure pipes. Placed in the piping system components, such as Apollo shut-off valves, bends, suction strainer, filter, and foot valve, will create more significant pressure loss.

Suctioning pipe

  • The goulds pump units need to be placed as closely as possible. 
  • The pipe should be as short as possible.
  • Run the pipe, so that slopes upward toward the goulds pump to prevent the formation of air pockets.
  • Placement of the suction pipe – BBA Pumps installation tips

If the slope of the pipe, the pipe must slope down towards the berkeley pump. Place the shut-off valve between the floating room and MP to prevent overpressure in MP.

Berkeley Pumps Installation Tips

  • Air pockets need to be avoided. This is done by ensuring the pipe is laid usually. 
  • Use the smallest possible number of bends.
  • The bend should have the largest possible radius.
  • The pipe system must be completely airtight.
  • In the case of Berkeley non-pump self-priming, in which fluid does not flow into the Berkeley pump, install a foot valve with flow capacity is large enough.
  • In the case of contaminated fluid, always put a suction strainer or solids separation with a widescreen clean opening large enough. Particle filtration size suction strainer must be equal to or less than the solids handling Berkeley pump specifications.
  • In the case of non-pump self-priming, in which fluid does not flow into the pump, install a foot valve with flow capacity is large enough.

When there is a change in pipe diameter, use an eccentric reducer to prevent the accumulation of air.

Ensure that sufficient fluid intake will remain submerged below the surface of the liquid so that at the lowest level, no air will be drawn.

Make sure the length of the pipe between the bend and Berkeley pump should be 4X that of the pipe’s diameter. A bend prevents the entry of liquid into the goulds pump impeller smoothness and can have a negative impact on the condition of suction.

BBA Pumps installation tips: 

  • When the fork is installed, use one with a bend inflow.

In the case of the goulds self-priming pump is equipped with a separate suction bend, this bend should not be removed or rotated.

For low viscosity fluids, either install a foot valve with a diameter equal to or greater than the suction valve or install a foot valve in the pipe without U-configuration (see technical specifications BA series).

Do not install the foot valve when pumping high viscosity liquids. Foot valve pipe causing additional losses.

To remove air or gas is present in the Berkeley pump or suction pipe, pressure pipe can be equipped with a bypass line. The use of the cut line will eliminate the air from the pump faster. See also ‘Pressure pipe.’

In some situations, the liquid temperature may be so high that it requires a pre-pressure pump relative to the NPSH inline (see technical specifications BA series).

pressure pipe

The designer is responsible for the installation, including security, such as protection against overpressure.

To prevent the loss of pipe, using the fewest number of bends possible.

When the long pressure pipe or as a non-return valve used in pipeline pressure directly after the Berkeley pump, install a bypass line equipped with a shut-off valve. Connect a shortcut to the suction line or the suction point.

Bleed air from the pump faster, cutting lines must be connected to a supply tank or the suction point.

WARNING

  • Prevent sudden closure pressure pipes. This will help in preventing the cause of water hammer.
  • A bypass, accumulator, or pressure safety needs to be installed if a water hammer occurs.

Suction strainer

When pumping polluted liquids or liquids containing solid particles, install a suction strainer in the suction opening.

When choosing a suction strainer, carefully consider the wide net that pipe losses kept to a minimum. The clean opening area of ​​the suction strainer must be at least three times the cross-sectional area of ​​the suction pipe.

In the case of contaminated fluid, always install a suction strainer with a clean open area large enough. Particle filtration size suction strainer must be equal to or less than the solids handling Berkeley pump specifications.
