Q. What is an additive injector system?
A. An additive injector system is required to inject fluid
additives directly into fluid products. Additive injector
systems are most commonly designed to add customer-
required additives to bulk fuel products during the
delivery process.
Q. How does it work?
A. The Hammonds injector acts as a fluid-powered
motor, borrowing just enough energy from the flowing
product to operate a diaphragm additive pump, injecting
the additive upstream of the fluid motor to aid in
blending.
Q. Can Hammonds injectors fit in my injection
applications?
A. Yes. Hammonds, having a full line of injectors, can
place an additive injection system anywhere in a flowing
product line. Installation may be made in remote
pipelines, at terminal racks, on delivery vehicles and
even injector units at the end of a fuel hose.
Q. What makes the Hammonds injector better
than other types of injection systems?
A. Hammonds injectors are all mechanical, completely
self-contained and compact units. They need no
electrical or air power to operate, making the unit ideal
for applications on remote unattended pipelines, on
delivery vehicles, or as additions to meet additive
injection needs to an existing delivery terminal rack.
Q. Why would I need an additive injector?
A. Batch blending is a very haphazard way of ensuring
that customer-required additives are evenly diluted
throughout the fuel product delivery. Many additives
have characteristics that are not conducive to even
dilution, making proportional additive injection even
more essential. The design of Hammonds injector
systems eliminates those problems by
continuous "proportioned to flow" additive injection.
Q. How accurate is the Hammonds injector?
A. Because the Hammonds additive injector acts as a
fluid motor, it is a linear response to the rate of product
flow. The faster the unit works, the more additive is
injected. So a linear correlation between product
delivery and required additive ratio is maintained no
matter what speed the fluid is being delivered. Because
the injection response is continuous, an even dilution of
additives results.
Q. Is it difficult to install a Hammonds unit?
A. It's as simple as a mechanical pipe connection, since
units can be customized to fit a customer's existing
piping. And because the Hammonds injection units are
free of external power requirements, you avoid
hazardous wiring conditions and additional ancillary
equipment.
Q. How much does it cost to install?
A. The Hammonds injector unit is the least expensive of
all available injectors because it's so simple to install.
Since the fluid motor acts both as a source of control
and power, the Hammonds unit requires no additional
meters, electrical connections, pulsers or pressurized
additive pumps. In many cases, complex competitive
systems are more costly to install than a Hammonds
unit costs initially, due to the competition's
requirements for concrete foundations and extensive
site engineering, explosion-proof pumps and pressurized
additive lines.
Q. What types of industry applications can
utilize a Hammonds system?
A. The injectors are used commonly in fuel and pipeline
delivery-type systems, aviation fuelers and heating oil
delivery trucks, hydrant systems, even water
applications in injecting additives into cooling towers
and boiler-feed circuits. Some of the new and more
innovative areas Hammonds has entered are
environmental applications such as fertiligation and
wastewater treatment plants.
Q. How long has Hammonds been making
injectors?
A. Hammonds injectors have been manufactured for
more than ten years. The first designs met the
requirements of the military in their need to have
injection equipment in remote or combat-battlefield
conditions, where electrical requirements and meters
are not readily available, and is used today almost
exclusively for treatment of a large percentage of U.S.
defense fuels.
Q. Will an additive injection system alter my
ability to deliver product in any way?
A. The differential pressure caused by a Hammonds
injector is minor, causing little change in line pressure or
gallon-per-minute flow during delivery. Therefore, there
is virtually no change in the ability to deliver the
product.
Q. What benefit would an additive injector
system have for me?
A. The primary benefit is accurate, evenly diluted
additives meeting the customer's specifications. Also,
the ability to inject customer-required additives can
create a new market niche which translates to new
profit centers for an operator. It might even result in
increased sales, as some additives require that the
treated tanks be filled completely.
Q. Where would I install an additive injector?
A. Hammonds injectors are designed to be located
downstream of the product delivery pump. The additive
injector point is placed before the unit's fluid drive to
aid in blending. However, if the unit is to be placed
upstream of the final filtering system, Hammonds
recommends that the additive injection point be
relocated downstream of that filter system.
Q. What is the most commonly used injector?
A. For pipeline applications, the 8T series is used due to
the high product flow rates. In terminal or rack delivery
situations, our 4- and 6-series injectors are most
suitable due to the common pipe sizes. The Hammonds
600 series remains the industry standard for truck-
mounted additive injection.
