We have discontinued the 150 psi shurflo pump, what we have left is whats in stock. All of the old Vari-Cool Videos, S-hSV videos and videos of our legacy products have been removed as to not confuse the user.
Our new pumps are the Aquatec bypass pumps that do not have the demand swich so do not pulse like the shurflo version we used previously. What the vari-cool did was set the dutycycle to the point to where the switch on the shurflo pump would not trip and then scale the dc between the min and max. The new CMGS / VC2 can do the same thing, but would only be necessary if someone mates them with a legacy kit.
