Roper® 70419 Pump Parts
7X419 crowned gear-joint progressive cavity pump parts
Roper®’s 2026 parts book explicitly identifies 7X419 components inside the SWG10 drive-end service block. ACCA Pumps supports aftermarket replacement and technical identification for applicable 70419 gear-joint components.
Roper® 70419 Engineering Overview
The 7X419 is explicitly supported by Roper®’s current parts documentation. Its service block uses the 412/19/28 gear-joint size grouping, including a 7X419/28 adapter flange and a 419-specific connecting-rod seal.
Crowned Gear Joint
Sealed gear-joint drive arrangement using hub and ring gears.
419-Specific References
Roper® explicitly lists P22-117 for 7X419/28 and G90-14/G90-33 connecting-rod seals for 419 service.
412/19/28 Service Group
Several drive-end components are published as common 412/19/28 references.

Before You Order
Confirm the complete 7X419 configuration
Provide the full figure, serial number, materials, stage count and existing component number. Roper®’s documentation groups multiple replacement configurations in the same drive-end block.
Progressive Cavity Engineering Note — Joint & Drive Reliability
The drive train must transmit torque while accommodating the eccentric motion of the rotor. Joint condition, lubrication, alignment and bearing support are therefore important to reliable PCP operation, especially as torque and differential pressure increase.
Frequently Asked Questions
Is 7X419 actually documented by Roper®?
Yes. Roper®’s 2026 parts book explicitly lists 7X419/28 adapter-flange and 419 connecting-rod-seal references and groups 419 with the 412/19/28 gear-joint service components.
Does 70419 use the same service group as every SWG10 replacement?
Not automatically. The parts book uses a shared service block but also contains model-specific descriptions. Final selection should use the complete pump identification.
