Flowserve ANSI History

Mark 2 Mark 3 Mark 3A Mark 3 ANSI 3A

Mark 2 Power End• Created in 1962

• Bearing Cap Fixed

• Cork or EPR gasket

• Impeller Setting via shims between bearing snap ring and housing

• No Sight glass oil level set by Trico Oiler

• Oil Flinger required because oil level not visually set

• Bottom Vented Breather

• Bearing span setting required no I.B. Bearing shaft shoulder

• Standard Lip Seals

Mark 3 Power End• Impeller adjustment via micrometer

threaded bearing carrier• Standard Lip seals• Oil level set visually with ½” sight glass

and Trico Oiler• Oil Flinger not required• Top Vented Breather • GP2 & 3 shafts and power end

interchangeable with MK2• Shafts machined with shoulders for

bearing span location• Gp1 shafts 1 3/8” through seal chamber• Larger oil sump• MK3 1J Power End created for MK2

replacement on GP1 using 1.125”

Mark 3A Power End• Threaded carrier changed to use

small dia. O-rings• Threaded carrier uses cast lugs at

hold down bolts for use of wrench to adjust

• Removed lugs on O.D. of carrier removing need for spanner wrench

• Larger Oil return slots provide in bearing Carrier

• Bearing housing designed for larger 1” bulls eye sight glass

• Oil sump increased over Mark 3• Standard lip seals• Trico Oiler combination Watchdog

style standard

seal

Features

• The FXP Seal is made up of a 316 SS Rotor, a stationary Glass Filled PTFE Disk, and a 316 SS Gland to retain the Disk.

• The Rotor face is tapered to provide a good match between the two parts and has concentric grooves machined into the sealing face. The concentric grooves provide sealing dams with high loading on each, providing consistent performance whether static or dynamic.

• The Disk is piloted to insure good concentricity of the sealing surfaces, thereby minimizing leakage.

Myth # 1Two Times More Wear Area = Longer Life, Reduced Repair Costs

Goulds Claims… The Truth Is…

• More working area being worn does not reduce the wear rate – it just damages more parts

• Adjusting open impellers towards the casing to compensate for wear increases the thrust loads from larger gap on backside causing seal chamber pressures to increase

• Cost to replace a rear cover is nearly 1/3rd the casing price

• Rear covers are much easier to replace than a casing (and can be resurfaced)

• Balance holes in the Reverse Vane impeller ensure hydraulic loads are similar in magnitude to open impellers

• If open impeller is required, the Mark 3 has this option available

Myth # 2Enclosed Impellers Cannot be Adjusted


• Reverse Vane impellers are not fully enclosed

• Reverse Vane impellers are easily adjusted using micrometer adjustment

• Nose ring wear does not affect performance until it is almost gone (this is not a wear ring)

• With open impeller adjustment Goulds has to choose either performance or seal chamber pressure renewal. They can’t get both. With the Reverse Vane impeller, one adjustment renews both!

Myth # 3Back Pump Out Vanes Control Axial Thrust


• Goulds back pump out vanes wear too, so they become less effective and controlling thrust loading and seal chamber pressure over time

• Pump out vane wear combined with moving the impeller away from the rear cover for “performance renewal” means that significant pressure increase occurs behind the Goulds open impeller which adds to the thrust loads and seal chamber pressure

Max Sphere Size• Percent of Sizes with the

Largest Passage Way– Flowserve: 86%– Goulds: 14%

Better Interchangeability

• Interchangeability Only 3 Mark 3 Power Ends cover all sizes.

If customer has 6x4-10, then only shaft is different.

• Less Stock Required Only 3 Power Ends – Goulds has 4 sizes Only 3 Seal Sizes – Goulds has 4 sizes All Group 1 pumps use the same rear cover size Goulds has 2 cover sizes for Group 1 pumps
