Update on Our Trademarked Products

UPDATE:  Triangle Pump Components Inc. (TPCI) is proud to announce that the CavPack® Valve Set, Resista® AR Valve, and the DynaRod® Extension Rods have been granted “Registered” trademark status!

Below is a review of the meanings behind the newly registered product names.

CavPack® Valve Set

TPCI’s standard CavPack® valve set uses the V7H and V7F Durabla® valves (derived from the Latin term for “durable”) to address the issue of cavitation in reciprocating pumps.

V7H X Durabla Model V7F

On the suction side, the lightly loaded spring on the V7H valve allows as much fluid into the chamber as possible and the heavily loaded spring on the V7F valve allows for maximum output by the plunger pump. This combination is the most effective valve set-up for Low Net Positive Suction Head (NPSH) applications (where plunger pumps are starved of incoming fluid on the suction side) thus helping to reduce one of the most common causes of cavitation and resulting in improved pump efficiency.


AR VALVEResista® Abrasion Resistant (AR) Valve

Derived from the Spanish word “resistente,” meaning strong, tough, and resistant, the Resista® abrasion-resistant (AR) valves are just that. Designed to be used in environments with fluid containing abrasive materials or small solids under high pressures, these valves are ideal for applications enduring heavy wear.


Metal PlungerDynaRod® Extension (Pony) Rods

Our DynaRod® pony rod name is derived from the Greek word “dynamis,” which means power. These extension (pony) rods are made of the highest quality stainless steel  coated in Colmonoy® (or other exotic metals upon request) for improved performance, durability, and life expectancy.
