Questions & Answers

What are the connections on the pump suction and discharge?
The inlet is tapped 1 female BSP (British Standard Pipe) and is intended to mate with the included 1 male BSP suction tube. The outlet is tapped 3/4 female BST (British Standard Pipe) and is intended to mate with the included 3/4 male BSP spout.
Can I connect the pump to male NPT pipes?
The pump should only be connected to the included suction pipe and included discharge spout
What is the difference between NPT and BSP threads?
NPT and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most diametrical sizes have a different pitch. NPT threads have a 60° included angle and have flattened peaks and valleys; BSP threads have a 55° included angle and have rounded peaks and valleys. Never try to mate a BSP fitting with an NPT fitting if the pressure holding capability is at all critical.
