The Roosa Pump and the Moen Faucet

The Roosa Pump and The Moen Faucet

In May 1947 a deal was made with Vernon D. Roosa to come to Hartford Machine Screw and perfect his fuel injection pump for diesel engines. The project initially cost more than expected with some directors in favor of abandoning, but by 1952 major bugs had been eliminated and the product was ready for market. Demand for diesel pumps climbed steadily through the 1950s and 60's. However, the oil crisis of the 1970s and General Motors' decision to install diesel engines in passenger cars, significantly stimulated pump sales. By the end of the decade, sales neared $120 million. In 1956, a deal was struck with Ravenna Metal Projects to acquire the company's first real consumer product the single-handle faucet developed by Alfred M. Moen. After a series of false starts, the company initiated a program to sell exclusively through plumbing wholesalers. This was later adapted to include retailers, and during the 1970s Moen sales rose from $40 million in 1972 to $100 million in 1979, one quarter of Stanadyne's total revenue.

Blake and Knowles Steam Pump Company National Register District

The Blake and Knowles Steam Pump Company National Register District encompasses the historical industrial complex of the Blake and Knowles Steam Pump Company and its successor, the Worthington Pump and Machinery Corporation in East Cambridge, Massachusetts. It is located in a one-block area surrounded by Third, Rogers, Binney, and Fifth Streets. The property was developed by the Blake and Knowles Steam Pump Company, one of the nation's leading manufacturer of industrial pumps from the late 19th century into the mid-20th century. The district was listed on the National Register of Historic Places in 1997.

Fire pump

A fire pump is a part of a fire sprinkler system's water supply and powered by electric, diesel or steam. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes. A fire pump is tested and listed for its use specifically for fire service by a third-party testing and listing agency, such as UL or FM Global. The main code that governs fire pump installations in North America is the National Fire Protection Association's NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection. Fire pumps function either by an electric motor or a diesel engine, or, occasionally a steam turbine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize, when connected via a listed transfer switch, the installation of an emergency generator. The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature, and opens, releasing water. Alternately, other fire hoses reels or other firefighting connections are opened, causing a pressure drop in the fire fighting main. Fire pumps are needed when the local municipal water system cannot provide sufficient pressure to meet the hydraulic design requirements of the fire sprinkler system. This usually occurs if the building is very tall, such as in high-rise buildings, or in systems that require a relatively high terminal pressure at the fire sprinkler in order to provide a large volume of water, such as in storage warehouses. Fire pumps are also needed if fire protection water supply is provided from a ground level water storage tank. Types of pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.

how often would i need to pump?

Breastfeeding comes easy to some and very difficult to others. You are best to hold off on buying a pump all together until you know how you and your baby are going to jive. Therefore, I end up having no choice but to feed my son with formula. Still determined to breastfeed I bought a Medela double pump and have now restored and surpassed my original milk production. My baby is now 10 weeks old and is fed breast milk exclusively. All different breast pumps work better for different moms In the event that you have no troubles producing milk and your baby has no problems latching then an inexpensive manual, or mini eletric pump would work fine. Medela's website actually has a buying guide for what pump will suit your needs best, however, in my experience it is best to hold off making any descisions or purchases until you know the needs of your baby
