[Steam-engine] Penberty Injector info please

[Bruce & Marlene Babcock]

Richard,

    According to a modern, June 1987, Penberthy brochure an AA-21 is a 
standard 1/2 inch injector that, with three feet of lift, will deliver150 
gallons of water per hour at 40 psi steam, 175 gallons at 60 psi, 180 
gallons at 80 psi, 165 gallons at 100 psi, 155 gallons at 120 psi, and 150 
gallons at140 psi.

    According to an old Penberthy brochure (no date) an A-22 is a 1/2 inch 
injector.  Capacity per hour with 1 to 3 feet of lift with a steam pressure 
of 60 psi is 135 gallons per hour, and at 110 psi it is 70 gallons per hour. 
This same brochure indicates that the AA-21 will deliver 180 gallons per 
hour with 60 psi steam and 100 gallons per hour with 110 psi steam.

    I am affraid that I am raising more questions than I am answering.   It 
appears that it is important to know the age of your AA-21 injector if you 
want to know its characteristics at any pressure other than 160 psi.  The 
address on the old brochure is Windsor, Ontario and Detroit, Michigan, if 
that helps anyone to establish the date.  If I had to take a wild guess I 
would say the brochure was printed in the late 1930s or in the1940s.

    I hope that someone else can be of more help.    Stellar Industrial 
Technologies in Lancaster, Ohio (740) 654-7052 is a Penberthy distrubutor.

Sincerely,

Bruce E. Babcock
