Roper® 70205 Maintenance Recommendations
Inspect Pin-Joint Wear
Inspect pins, bushings, bores, connecting-rod ends and retaining hardware together.
Review Bearings and Seals
Inspect bearing and sealing components whenever the drive end is opened for major service.
Verify Packing Arrangement
Record packing gland, packing and sealing arrangement before disassembly.
Confirm Rotor/Stator Match
Use the complete figure number and material specification when replacing pumping elements.
Protect Stator Installation
Use compatible assembly lubricant and avoid damaging the elastomer during installation.
Avoid Dry Running
Prime with compatible process fluid before startup and confirm an open discharge path.
Progressive Cavity Engineering Note — Low-Shear Pumping
The progressing cavities move product with smooth, controlled displacement, which is one reason PCP pumps are used for viscous and shear-sensitive fluids. Correct speed and pumping-element selection remain important for the specific product.
Frequently Asked Questions
Which Roper® pump figures are covered by the 70205 page?
This page covers 71205, 72205, 73205 in the Roper® 70200 pin-joint family.
How do I identify the correct Roper® 70205 replacement part?
Use the complete Roper® figure number, serial number, construction and existing part number. Material and elastomer differences can change the applicable replacement part.
Can I order individual pin-joint components?
Yes. ACCA can support individual drive-train components for applicable configurations, but mating wear parts should be inspected together during overhaul.
How should I select a rotor or stator?
Confirm the complete stage-specific figure and construction. The Roper® parts book documents multiple rotor materials, finishes and stator elastomers for many sizes.
Does ACCA supply complete replacement pumps?
ACCA can support replacement components and complete progressive cavity pump solutions for supported applications. Contact ACCA with the installed pump information and operating conditions.
