LTC Miniature Diaphragm Pumps are offered in both brush and
brushless DC motor drives that can be configured for your specific
performance requirements and handle a wide range of liquid
media over a wide range of pressures. LTC’s patented Fluid-Blok™
Advanced Sealing Technology provides redundant sealing capabilities
to eliminate potential leaks. Monolithic diaphragm design enables
maximum suction, priming, and continuous dry operation. Ideal for
waste, transfer and bulk movement of liquids. |
| |
| Features |
LTC Series Pumps set the highest benchmark for service free life-
expectancy with our advanced proprietary diaphragm elastomer. |
Port design allows for top or bottom face seal and is molded for
1/4-28 UNF threaded fittings. |
Overmolded diaphragm eliminates metal components in the
wetted path resulting in a design that is inert to variety of media. |
Incorporating the lightweight EZ Mount Accessory facilitates
simple system assembly while dampening vibration and reducing
noise levels. |
Our 100% oil and grease-free pump and compressor design
maintains the purity of your system and are commonly used in
FDA-approved systems. |
RoHS compliant. |

| Performance Specifications |
The above graph represents an example of performance for the pumps series handling water at 800 feet (244m) above sea level at 75°F (24°C). Performance
will vary depending on barometric pressure and media temperature. Curves are representative of standard pump configurations. Pump configurations could be
customized for higher or lower flows, depending on specific customer requirements.

| Electrical Integration and Motor Control |
 |
EZ Mount provides ease of installation and effective control of
vibration transfer. EZ Mount was designed to mount easily to the
Precision Fluidic LTC Family of diaphragm pumps. |
| |
| - Features |
Isolation feet on the EZ mount can be rotated in any one of three ninety-
degree planes and is designed for top-down or bottom-up mounting
providing simple installation. |
EZ Mount was designed to minimize weight added to the pump assembly.
Approximate weights are: Style A - 0.63 oz (18 g), Style B - 0.71 oz (20 g). |
Effectively absorbs vibration to minimize most vibration-induced noise and
vibration transfer into an instrument. |
| Designed to keep height and size to a minimum. |
| Engineered for Parker LTC pumps to ease integration into your system. |
