The sewage suction truck is one of the most important pieces of equipment that a contractor should own. It is a vehicle that helps in keeping the area around a building clean and safe from the corrosive effects of sewage. A contractor can purchase a sewage suction truck that is made from high-quality materials, has a hydrostatic drive for easy operation, and a safety guardrail. You can also choose from a low-volume sliding vane pump or a liquid ring pump.
Vac-Con chassis engine with hydrostatic drive

Vac-Con offers two lines of vacuum excavators. Both are designed for contractors and utility companies. These machines are designed to handle the toughest excavation jobs. Each unit has a unique design that adds power without compromising safety.

The Mudslinger line of compact trailer-mounted hydroexcavation vacuums have a 55 degree hydraulic dump hoist and 845 gallon debris tank. They also feature a 1,190 cfm blower. All of these units are designed to be portable and rugged.

Vac-Con's VecJet(tm) VJ375 is a 750 gallon water tank machine designed for the toughest sewer lines. This model is available in both single and dual engine designs. It is equipped with a powerful excavator and a hose reel operator station, making it a great choice for any contractor.

Vac-Con's XX-Cavator is a larger version of the X-Cavator. With its low decibel noise level, this machine is kind to operators. Using a chassis engine for the vacuum system, this machine eliminates the need for a clutch or gearbox.

Vac-Con's articulating hose reel articulates 180 degrees and can extend beyond the width of the vehicle. This enables the operator to work in any position.

The Vac-Con(r) Hydro-Excavator is a versatile tool that can be used to expose underground utilities. It features a vacuum system that can be controlled from the front hose reel control station.

Vac-Con's patented 3-stage fan increases vertical pull and loads faster than the competition. With its simple and safe design, this machine has a five-year warranty.

Vac-Con is a 100% employee-owned company. It manufactures more than 6,000 custom-built truck-mounted machines. Many of the components on these machines are made by Vac-Con in its own fabrication shop.
Low-volume sliding vane pump or a liquid ring pump

If you are looking for a reliable pump for a sewage suction truck, you may want to consider a low-volume sliding vane pump or a liquid ring pump. These pumps offer trouble-free operation and efficient performance.

Vane pumps are reversible and self-priming. They can handle a wide range of fluids. The main wearing part is a rotor. It has rectangular-shaped vanes mounted in slots on the rotor. Vanes are often constructed from carbon graphite.

Sliding vane pumps feature a revolutionary rotary vane design. Using this rotor design, they can produce a stable flow without imparting high shear rates. This allows for excellent dry-run capabilities.

Moreover, sliding vane pumps are easy to maintain. They require less horsepower than other types of pumps. They are also a good choice for mobile equipment applications.

Typically, sliding vane pumps are designed for low-to medium-viscosity fluids. However, they are not suitable for use in highly viscous applications. Despite their efficiency, they are not ideal for high pressure installations.

Alternatively, a liquid ring pump is a simple and reliable vacuum pump that offers even suction. The suction is maintained by compression chambers formed by the ring of liquid. As the ring rotates, the gas trapped in these chambers reports to a discharge port in the end of the pump casing.

Liquid ring systems are available in single-stage and multi-stage designs. Two-stage designs can generate 29 inHg of vacuum.

Choosing a vane pump or a liquid ring vacuum pump is a matter of evaluating all the operating conditions. Depending on your specific application, you will need to pick a pump with the right drive for the job.
Diaphragm mud pumps

If you are in the market for a sewage suction truck, you might be considering using diaphragm mud pumps. Unlike traditional designs, these units are lighter and easier to handle. They are also cheaper overall. These pumps come with self priming capabilities and have 10" semi-pneumatic wheels.

These pumps are perfect for wastewater treatment plants, industrial waste, seepage dewatering, and marine tanks. Typically, they have inlet and discharge port sizes that range from 1/4" to 4".

A diaphragm pump can be air or electric operated. However, most of these are air operated. The main parts of the pump include a central air valve, a diaphragm, and a delivery manifold. Diaphragms can be made of various materials, such as PTFE, NBR, or aluminum alloy.

When choosing an air operated diaphragm pump, you will need to consider the types of applications that you plan on using it for. For example, do you need to use it with high viscosity fluids? Also, are there air leaks or pressure issues?

A good rule of thumb is to change the diaphragm after 300 hours. This will avoid major damage to the pump and the diaphragms. To make sure that you are purchasing the right model, you will need to check the manufacturer's specs. You can also use a pressure gauge to measure the pump's performance.

In addition to these factors, you will also want to ensure that you are properly installing the pump. Check the pump's manual for a detailed listing of instructions for the correct RPM speed and pressure.

Then, you'll need to examine the suction line. Problems can arise from leaky fittings or clogged filters.
Safety guardrail

When a sewage suction truck is being used for a cleaning job, safety guardrail is a great way to protect the vehicle and its crew. The vehicle can also be used as a fire truck in case of emergency. In addition, it can be easily installed and maintained.

There are two types of safety guardrails. The first type is an internal shield with a square guard rail to support the water filled pipe inside. This is the most common. Another option is an injector. It is preferable to use an injector because it eliminates the need for a water filling pipe inside the shield.

Generally, the height of a guardrail is 42 inches to 45 inches. However, the height may deviate by a nominal amount. For example, if a guardrail is 48 inches, the corresponding handrail must be 19 inches in length. If the handrail is not 19 inches, the handrail must be at least 24 inches long.

A road guard-rail cleaning vehicle is a new type of sanitation cleaning vehicle. Its power is provided by a hydraulic lifting arm, side engine, and hydraulic motor. These components are arranged on a frame of a sliding block. The hydraulic system also includes a limit spring, a hydraulic pump, a hydraulic oil container, and a reversing valve.

Normally, the guardrail is brushed by two rows of brush rollers. They are arranged on the top and bottom of the truck and drop into pockets in the frame. This allows the operator to keep his or her eyes on the manhole. Alternatively, an access ladder can be placed in the side pockets to allow for convenient access.
Street flushing, chemical and water-spraying services

A street flushing, chemical and water-spraying operation is in the works, with some neighborhoods already on the hook. The flushing process is a routine maintenance operation that should last for at least a couple of years, depending on local weather conditions and other factors. During the flushing phase, residents should use caution and be aware of the crews as they work their magic. In addition, avoid allowing your dog or child to play with the water as it may find its way into the faucet. Similarly, don't forget to switch off any water-using devices such as hoses, lawn sprinklers or pool filters.
