I say STAY AWAY FROM THESE PUMPS! I recently got one of the stainless steel versions, and the input fitting was an NTP fitting, and the output was a BSP fitting...I think. In any case I could only thread my stainless steel quick disconnects onto one side, and only half way.
They were not helpful at all by email. They kept telling me to try a BSP fitting even though their site said they took NTP/BSP fittings whatever that means.
Do yourself a favor and buy a March pump.
