Frequently Asked Questions
Q. "What materials are used to make the SCALA2 pump?"
A. Most of the pump is made of Noryl FE1630PW Polyphenylene Oxide (PPO) mixed with Polystyrene (PS) which is a 30 % glass reinforced injection moldable grade plastic. The pressure tank is made of 304 stainless steel and Noryl with a Butyl diaphragm. The combined pump and stationary portion of the electric motor housing is 304 stainless steel and aluminum surrounded by Noryl. The pump shaft seal is made of carbon and ceramic.
Q. "These pumps are supposed to be relatively quiet, but after installing my pump I am hearing some vibration noise in a room next to where the pump is installed. Is this normal?"
A. This is not normal, but sometimes vibrations from the pump can be transferred to the building structure if rigid piping is not braced correctly or if flexible connectors are not used for installation. Here are a few suggestions that may help reduce noise and vibration: (1) Install a rubber pad underneath the pump and make sure the pump is tightened to a solid horizontal foundation using screws through holes in the base plate. (2) Use flexible water connectors to the inlet and outlet ports of the pump instead of rigid piping directly plumbed to those ports. (3) Make sure rigid pipes are tightly secured with pipe hangers close to where they are joined to the connections of any flexible connectors used. Insulating the pipes before the pipe hangers are attached can also help deaden sound travel.
Q. "Do these pumps include flexible pipe connectors?"
A. No, they are not included with these pumps. Flexible pipe connectors must be purchased separately. The inlet and outlet male pipe thread ports do have limited flexible movement of ± 5° to help the installer connect piping to the ports.
Q. "Is the SCALA2 pump maintenance free?"
A. The SCALA2 pump is virtually maintenance free. The manufacturer does recommend the pump owner check the inlet and outlet non-return valves once a year or as needed and clean with warm water and a soft brush if necessary. There is also an insect filter on the bottom of the pump to prevent insects from nesting inside the pump. This insect filter can easily be removed and should be cleaned at least once a year with a stiff brush.
