 One component often overlooked in a
sewage ejector installation is the guide rail system. Many people never give them a second
thought until a pump fails. Often times an existing guide rail system can pose a problem
when replacing a pump with a different model or brand than the original system. To assist
during these circumstances Zoeller Engineered Products has released a series of new
components to make our pumps compatible with existing rail systems.
The
first series of components focuses on existing Flygt pumps. Currently available and ready
for immediate shipment is the Flygt Rail Adapter Kit to adapt any pump to an existing
Flygt 4" (Zoeller part number 6039-0048) or 6" (Zoeller part number 6039-0053)
rail system. The adapter kit will be included in your catalog on the back of ZM1347 in the
Accessories and Controls section. Each adapter kit includes a cast iron mounting plate,
flange gasket, and stainless steel mounting bolts. Now, any pump that uses a standard ANSI
4" or 6" mounting flange can be adapted to a Flygt rail system.
The
second series of components focuses on Hydromatic pumps. The first kit available is for
Hydromatic S4L pumps (Zoeller part number 6039-0052). This kit adapts Zoeller models
6771-6773 with 4" discharge to the Hydrorail 4" guide rail system using the
existing Hydromatic sealing flange and pump cradle. The second system is for all 6"
discharge Hydromatic pumps (Zoeller part number 6039-0049). This kit adapts all Zoeller
models 6650-6671 and models 6760-6773 pumps with 6" discharges to the Hydrorail
6" guide rail system using the existing Hydromatic sealing flange.
Remember,
Zoeller Engineered Products standard lead time is two weeks but in emergency situations a
pump can be shipped within one or two days. Guide rail adapters are in stock and ready for
immediate shipment.
In addition to the above guide rail system adapters, Zoeller Engineered Products also
offers 4" (Zoeller part number 6039-0016), 6" (Zoeller part number 6039-0018),
and 8" (Zoeller part number 6039-0019) guide rail design of its own. All Zoeller
guide rail systems come fitted with stainless steel hardware and a buna-n seal. Rail
systems engineered for locations requiring non-sparking systems have a bronze rail plate
and brass guide brackets. Non-sparking systems are offered for 4" (Zoeller part
number 6039-0017), 6" (Zoeller part number 6039-0020), and 8" (Zoeller part
number 6039-0034) discharge pumps.
Zoeller
uses only one guide rail design for each discharge size. This is important because any of
our pumps will fit this same system with no modifications providing the discharge size is
the same. Many guide rail systems, offered by others, are only compatible with the
original model of pump the lift station was designed to use. If the demand on the station
has changed, dictating the use of a different model, then the end user could be left with
no other alternative but to purchase an entirely new system.
Another important feature of the Zoeller guide rail system is the compatibility with other
pumps. Should a sewer district have many different brands of spare pumps in case of a
failure, then any pump using a standard ANSI flange and the same size discharge as the
rail system can be used.
Zoeller
guide rail systems use a replaceable buna-n seal between the discharge of the pump and the
rail elbow. This seal provides more efficient operation than metal to metal type seals
because of less leakage during pump operation. By using a seal Zoeller can design a rail
system that uses greater mechanical tolerances to its advantage. These wider tolerances
can make the pump slide up and down the rail system with less likelihood of getting hung
up, which in turn provides easier installation and removal. Wider tolerances also allow
our system to be compatible with other brands of pumps without any special modifications.
Ease of installation and low maintenance are just some of the many positive comments we
have received about the Zoeller guide rail system. No complicated assembly or adjustment
procedures are needed. In fact, we have not heard of any problems from the field about the
rail system during installation or operation.
A
guide rail system’s design is usually not an issue during the purchase of a new
sewage system. Only when the original pump fails does this become a problem. The Zoeller
guide rail system offers competitive features that need to be recognized during the
initial installation of a sewage pit. These features could save many headaches down the
road.
Should any questions arise about the interchangeability of another brand and a Zoeller
pump help is just a phone call away. Zoeller’s Technical Service Department has five
highly trained personnel to help with any capability requirements that may come up during
the replacement of a pump. Call 1-800-928-PUMP and press 6 for Technical Service.
