Heavy-Duty Construction: The MAX® Series heavy duty shaft and bearing design make it last even when operating at high differential pressures for extended lengths of time. Its solid construction and oversized heavy duty bolts will minimize pump distortion caused by piping misalignment. The pump mounting bracket is made of corrosion-resistant 316 Stainless Steel or sturdy Cast Iron.
Configuration: The MAX® Series pumps are available in either Single or Double Mechanical Seal or Mag-Drive configurations. The universal seal housing will accommodate either a single or double mechanical seal. The Close-Coupled design eliminates difficulties and inconveniences of manually aligning the pump and motor. MAX® Series pumps are offered in 316 Stainless Steel or Titanium housings with a selection of internal component materials to optimize your selection for specific applications.
Magnetically Coupled (sealless): The magnetically coupled or mag-drive pump is the best method for handling toxic, noxious, crystallizing, or most other hazardous liquids since it completely contains the pumpage by isolating the drive shaft inside the pump housing. With no dynamic seal to leak or replace, the maintenance issues associated with seal leakage are eliminated. All Liquiflo® gear pumps are available with magnetic drive.Mechanical Seal: Mechanical seals are offered in single and double configurations and are used for chemical applications where leakage needs to be minimized or eliminated. The single internal mechanical seal is the most common seal type and is ideal for pumping clean liquids up to 5,000 cP viscosity. The double mechanical seal requires a flushing system and is typically used when pumping liquids that are viscous, abrasive, crystalize on contact with air or are very hazardous. Carbon vs. SiC seal faces are the primary choice for most applications up to 500 °F. SiC vs. SiC seal faces have high abrasion resistance and can be applied up to 500 °F.
Repair Kits: Repair Kits simplify inventory and speed repair. All parts can also be purchased separately. (See also Replacement Cartridge for even quicker repairs.)
Relief Valves: Positive displacement pumps should be installed with a relief valve in the discharge line to protect the pump and piping against any type of line blockage including the inadvertent closing of an isolation valve. Liquiflo® manufactures two sizes of relief valves in both 316 SS and Alloy-C.
Clamp-On Temperature Control Jackket: Temperature Control Jackets can maintain the pump at either elevated or reduced temperatures. They are commonly used when pumping liquids that solidify or become difficult to pump when the temperature decreases.
Raised-Face Flanges: ANSI, DIN, and JIS Flanges are available to simplify piping connections and disconnections.
Base Plate Mounting: Liquiflo® gear pumps are available with base-mounts to simplify installation. Liquiflo® also offers base-mounts with or without the motor pre-installed.
Hard-Coated Shafts: Hard-coated shafts are used to extend pump life in difficult applications requiring higher levels of wear resistance. Ceramic Chrome Oxide (CO), Tungsten Carbide (TC) and Titanium Oxide (TO) coatings are available.
