Mobile Pumps for Hazardous Fluids
Whether the problem be in-plant spills when transferring corrosive or hazardous chemicals from storage tanks or drums to process vessels, from pump or pipe joint leakage within the plant during maintenance procedures, from fluid line leaks due to pipe or tank damage from fork lift trucks within the facility, or for evacuating aggressive fluids from process vessels or storage tanks within or outside the plant, it is important to have mobile pumping equipment that can rapidly be taken to the area involved and safely handle the chemicals without electrical supply hook up.
Critical to the design of portable equipment for emergency or planned maintenance programs is the capability of these mobile system to handle a wide variety of aggressive process and waste fluids, including sodium hydroxide, hydrochloric acid, hydrofluoric acid, sulfuric acid, chromic acid, phosphoric acid and a broad range of metal cleaning, pickling, degreasing and other hazardous chemicals. For this reason, all fluid contact components are furnished in chemically inert thermoplastic materials such as polyvinyl chloride, chlorinated polyvinyl chloride, polypropylene and the various fluoropolymers. Even the steel pump shafts of these designs are sheathed in thermoplastics to isolate them from the corrosive fluids.
Here are two very different cases-in-point:

This interesting case in point involves a Vanton skid-mounted, diesel engine driven thermoplastic pumpset built for Specialist Chemical Cleaning Company NESS in England. This mobile pump unit was required for a chemical recovery system serving a series of remote sumps filled with corrosive waste fluids. It consists of a Vanton 6x4x13 polypropylene end suction horizontal centrifugal pump with an incorporated cyclone separator that permits the cleaned fluid to cool the mechanical seal as it returns the sludge to the volute. The rubber tired steel trailer with its industrial direct drive eliminates the need for electrical power supply and makes it feasible to service these sumps during planned plant shut down periods. (see
Figure 1)
A very different case in point is the application of a compact Vanton Flex-i-Cart® thermoplastic portable pumping system that consists of a Vanton Flex-i-liner® self-priming sealless peristaltic type rotary pump
mounted on a sturdy, wheeled hand cart to facilitate movement within the plant. It is ideal for handling chemical spills, leakage clean-up or evacuation of toxic, corrosive or hazardous spills. The pump is designed with no stuffing boxes, glands, shaft seals, check valves or gaskets, and is available in the user’s choice of polypropylene, polyethylene or Teflon bodies and a selection of seven (7) different elastomeric replaceable liners. These are the only components in contact with the fluids to be pumped.
The compact unit shown is a Duplex model of sanitary design supplied to a leading pharmaceutical firm. Features include quick disconnect knobs for rapid servicing, a variable speed motor and a convenient control panel mounted near the handle of the skid to which the pump is bolted. The pump is furnished in polished stainless steel but all fluid contact parts –the body or casing, the flexible liner and the fittings are chemically inert nonmetallics.
