• Page 6: Introduction

  LPLT Filter Press Instruction Manual Introduction Fann’s Series 300 LPLT Filter Press is used for measuring filtration and wall- building properties of drilling fluids and cement slurries. The filtration rate is the fluid loss measured in milliliters at ambient temperature and 100 psi (690 kPa) through a special filter paper for 30 minutes.

  LPLT Filter Press Instruction Manual Document Conventions The following icons are used in this manual. NOTE. Notes emphasize additional information that may be useful to the reader. CAUTION. Describes a situation or practice that requires operator awareness or action in order to avoid undesirable consequences. MANDATORY ACTION.

• Page 8: Safety

  LPLT Filter Press Instruction Manual Safety Safe operation of filter presses requires that the laboratory technician or drilling fluids engineer be familiar with the proper operation and potential hazards associated with this equipment. For instance, if the filter cell or pressurization equipment has a leak, then sample or pressurizing fluid could be released and cause serious injury.

  LPLT Filter Press Instruction Manual 2.1.2 Pressure Regulators  Maintain pressure regulators in good condition. Never use oil on pressure regulators.  Pressurization systems that leak should be repaired or replaced.  Gauges, fittings and hoses should be kept in good condition and leaks should be corrected.

• Page 10: Features And Specifications

  LPLT Filter Press Instruction Manual Features and Specifications This filter press is used in a static filtration test to measure fluid loss and filter cake characteristics of drilling fluids. The basic filter press assembly consists of the filter press unit and accessories, listed in Section 10.

  LPLT Filter Press Instruction Manual Dead-Weight Hydraulic Pressure Source The Dead-Weight Hydraulic Filter Press is a Series 300 Filter Press equipped with a dead-weight hydraulic assembly. See Figure 10-6. Follow this procedure to pressurize the filter press with the dead-weight hydraulic pressure source.

• Page 15: External Pressure Source

  LPLT Filter Press Instruction Manual External Pressure Source A compressed air source that supplies more than 100 psi (690 kPa) is suitable to pressurize this filter press. A regulator is required. You can attach any regulator that meets the specific requirements for compressed air, nitrogen or carbon dioxide.

• Page 16: Installation

  LPLT Filter Press Instruction Manual Installation The filter press can generally be arranged to suit the available space and the desires of the lab personnel, consistent with any established work processes. Consideration should be given to the location where samples are prepared and the cell is cleaned following test completion.
