New Magnatex Pumps For

No-Leak Applications

Magnatex Pumps Inc. introduced the MP/MPL Series of high-effi- ciency, close-coupled, magnetically- driven sealless centrifugal pumps, designed specifically for low-flow, high-head applications in corrosive, noxious or toxic services, where leak- age cannot be tolerated. The pumps are available in nine sizes in stain- less steel. Alloy 20, or Hastelloy C construction, with capacities from 1 gpm to 150 gpm. Handling head to 400 ft. (121.9 m); temperature to 300 degrees F; working pressure to 225 psig; and one- to 20-hp models are available.

The MP/MPL Series utilizes

Magnatex Pumps' exclusive straddle-bearing design to provide longer life in a wide range of corro- sive applications in chemical pro- cess, pharmaceutical, pulp & paper and other industrial plants.

APL Applies For MarAd

Permission On TMM

Cargo Exchange

American President Lines (APL) filed an application with the Mari- time Administration for permission to use space on vessels operated by

Transportation Maritima Mexicana

SA de C.V. (TMM) for carrying car- goes in U.S. foreign trade.

The permission requires a waiver of section 804(a) of the Merchant

Marine Act, 1936, which precludes subsidized U.S.-flag operators or their affiliates from operating for- eign-flag vessels which compete with essential U.S.-flag shipping services unless the Secretary of Transporta- tion waives the provision for a spe- cific period of time. It has been assigned Docket S-907, and is being published in the Federal Register.

APL entered into a slot charter agreement with TMM in foreign-to- foreign trade between Asia and

Mexico. TMM's ships in the trans- pacific service provide weekly ser-

Naval ships, fleet oilers, commercial containerships, tankers and dredges are successfully finding new ways to operate more efficiently at lower cost, by utilizing

Tranter's unsurpassed plate-type heat exchanger technology. Schematics presented here illustrate typical ways they are doing it.

Superchanger® plate and frame heat exchangers are used in a wide variety of shipboard applications—particularly for cooling main engine jacket water and cooling main engine lube oil with fresh water or sea- water; cooling the ship's central fresh water; cooling electronic equipment; or recovering heat from condensate. They are far more effi- cient than tubular systems, and provide heat transfer coefficients from two to five times greater than those achieved by shell and tube units. They also require 10% to 50% less deck space and weigh up to one-sixth less.

Superchanger units can be equipped with titanium plates which offer the best resistance to corrosion and erosion when exposed to seawater. Intermixing or cross-contamination of hot and cold liquids is virtually impossible.

Low fouling rates reduce cleaning require- ments for Superchanger units, that are designed for easy maintenance. They can be cleaned-in-place by backflushing, or quickly disassembled by hand, cleaned and put back in operation.

PlatecoiP prime surface heat exchangers offer optimum temperature control. A Platecoil bank-in-tank unit provides wide interspaces for effectively passing solids while efficiently heating seawater containing oil from spills.

Platecoil bayonet heaters provide a large amount of efficient primary heating surface in a single unit for maintaining desired temper- atures in storage tanks. These heaters help promote convection currents for better heat transfer rates and tank temperature uniformity.

Platecoil suction heaters provide immediate heating for pumping oil out of tanks.

Tranter plate-type heat exchangers can be supplied in full compliance with codes and specifications as required by the ABS; the

U.S. Coast Guard; shock testing per MIL-S-

Circle 275 on Reader Service Card 901C; vibration testing per MIL-STD-167-1; and ASME U stamp per Sec. VIII Div. 1.
