Hargraves Pump Story

Hargraves didn’t stop there!

Despite the overwhelming response from fluidic system developers, the Hargraves team did not rest on their laurels. Employing a continuous product improvement process, they saw other opportunities to increase pump performance and efficiencies. Other improvements to their pump technology include increased pump head efficiency by improving the pump chamber, eliminating leaks, and optimizing the valve system.


Reduced noise levels

With ongoing customer demand to reduce audible noise levels produced by pumps, new design models have been routinely tested to discover the effects related to the pump operating sound levels. Hargraves’ advancements in motor technology and valve designs indicated above have contributed to significantly reducing pump noise.


Effective leak prevention

Leaks in pump heads have often been an issue in miniature style pumps, especially with liquid pumps. To this end, Hargraves has developed new sealing methods for both the diaphragm and the gasket used to seal the joint between the chamber and head. Termed Fluid-Blok™, pressures in excess of 60 psi have been achieved with absolutely no evidence of leaks.


The evolution of BTC-II, BTC-IIS, CTS and LTC Pump Series

The success of the BTC spawned new challenges from customers for other demanding applications. The need for increased flow from a dual-headed version in series derived the BTC-II. The BTC-IIS was developed to meet pump applications that required the ability to operate both pressure and vacuum with the same pump. The CTS Series met the requirements for lower flow and pressure requirements but fitting in a much smaller envelope. The LTC Series was developed for customers that demanded high efficiency and the elimination of leakage for their high performance liquid applications.
