Warren Rupp redesigned the Sandpiper HDB 1 1/2 AODD pump to incorporate all bolted construction, instead of the previously used v-band clamps.

The HDB 1 1/2 is a heavy duty ball valve pump that fits 1″ to 1.5″ pipe.  Warren Rupp has redesigned it so that it now has all bolted construction.  The HDB 1 1/2 completes the full line of HDB all bolted construction pumps! and became available October 1, 2008. 

The advantages of all bolted construction vs v-band clamping are: 

• Instant alignment = ease of maintenance
• Uniform torquing of seal = tightness against leaks
• Maintains seal after repeated servicing = lower repair costs
• Withstands four times the pressure versus V-band clamps

• Eliminates leakage at high pressure and deadheaded conditions
