Pump abuseability by design
examples and reasoning are more helpful than opinions..
Pitch in some real examples of PUMP failure if you can..
based on the "nothing else was wrong" senario,
or a small problem caused a "big repair bill"
(from 30 years experience in the service dept...)
example:
1.) pump was run 1/2" low on a General TS2021 cuz the site-glass was bashed-in-to,
and running at 3500psi it overheated the aluminum alloy rods and puked a rod.
2.) an AR pump was run 1" low on oil 'cus a piston seal started leaking.
that went un-noticed for 20 hours since the scheduled oil check. (has hour meter).
We inspected the rods and found NO signs of overheating, put the new piston esals in,
and it runs like a champ.
Looks to me like forged bronze rods can take MUCH more heat abuse than Aluminum alloy. Eh?
Most of AR, Comet, and Giant pumps have froged bronze rods.
Ibelive Udor does too, a few General have 'em,
Cat does not, ..not the ones I've seen
the General TS series does not,
and the General TSF series.. are so much more expensive for parts than AR and Comet,
I can't recommend 'em.
Another REAL important topic here is the pungers..
if they don't crack, you don't have to replace 'em..
TS2021's EAT plungers.. add that to almost EVERY repair bill.
I love 'em for repairability, and parts cost are still down there, kinda,
but those thin plungers are way too easy to break..I can't keep 'em in stock.
Comet and AR and Giant plungers are THICK and BEEFY by comparrison,
and I never sell 'em.. they just sit there dusty.
I sell for VALUE.. RELENTLESSLY..
I recommend, based on te above, AR and Comet, Giant, and the 3 plunger Udors.
add your examples for all to share
