Drilling Fluids
The RIGCHINA low pressure/low temperature filter press design features a cell body to hold the
mud sample, a pressure inlet, and a base cap with screen and filter paper. Suitable for field and
laboratory use, these units have become the industry standard for low pressure/low temperature
filtration testing.
RIGCHINA also manufactures other types
of filter press units and inventories a full
line of replacement and consumable parts.
Stainless steel cases are available for most
of the units. When several tests must be
run simultaneously, as in a laboratory
environment, multi-units are available in
either two, four, or six- cell designs. These
multi-units come complete with manifolds
and all necessary air hoses and bleed-off
valves. The field portable units are supplied
with various pressurization assemblies and
manifolds and rely mainly on carbon
dioxide bulbs and nitrogen gas to provide
pressure. The American Petroleum
Institute (API) recommends a standard
100 ± 1.0 psi (690 ± 6.9 kPa) cell pressure
be applied within 30 seconds for a 30
minute test.
When high pressure and high temperature
filtration measurements are required,
HTHP filter presses designed specifically for
simulating down-hole conditions are
recommended. Test temperatures for all
models may exceed 200°F (93°C),
provided a back-pressure receiver is used
to collect the filtrate. The components of
the RIGCHINA HTHP filter presses are fully
interchangeable with those marketed by other manufacturers. Three different sizes are available
to accommodate different requirements and preferences. All HTHP units may be ordered with 115
Volt or 220 Volt power requirements. A multi-unit laboratory model is available and may be
custom designed to your specifications. A wide variety of accessories and replacement parts are
also available.
Filter Press API (LPLT) Model RCLF-1A
Measuring filtration behavior and wall-cake building characteristics of a mud is essential to
drilling fluid control and treatment. The characteristics of the filtrate, such as oil, water or
emulsion content, are also fundamentally important. The types and quantities of solids in the fluid
and their physical and chemical interactions affect these characteristics. Temperature and
