Black widow spider bite facts nr 3 Even a large, female black widow spider can only inject a very small amount of venom in one bite. Unlike the small insects that the black widow spiders feed on, a human will therefore usually dont die after a black widow bite. Our large bodies can diffuse the venom and gradually break it down.
Fuel dispenser. A fuel dispenser is a machine at a filling station that is used to pump gasoline, petrol, diesel, CNG, CGH2, HCNG, LPG, LH2, ethanol fuel, biofuels like biodiesel, kerosene, or other types of fuel into vehicles. Fuel dispensers are also known as bowsers (in Australia), petrol pumps (in Commonwealth countries), or gas pumps (in North America).
A drum pump, also called an oil drum pump or oil barrel pump, is used to remove liquids from barrels, drums, tanks, and intermediate bulk containers (IBCs). Drum pumps consist of an intake tube, a pumping mechanism, an outflow hose, and often a nozzle of some type. Drum pumps come in many forms from the rotary type to a variety of other styles including lever, piston, siphon, double diaphragm, electric, and air. The 55 gallon drum pump is most common, because it is a standard drum size. The intake valve of a 55 gal drum pump is inserted into a bung hole, and the pump sits atop the barrel. The siphon drum pump, lever-action, and rotary drum pump, due to their simplicity, are the most commonly used type of 55 gallon drum pumps. An electric barrel pump reduces the time required to dispense liquids.
