A landfill well pump is pneumatically powered to pump landfill liquid from a landfill well. The landfill well pump includes a choke on the pneumatic exhaust of the pump. The choke regulates flow the driving gas out of the landfill pump, maintaining pneumatic pressure in the pump and metering inflow of landfill liquid into the pump.

A soil sampler includes a base and a plunger insertable into the base. The depth in which the plunger is inserted into the base determines the size of the sample collected by the soil sampler. The depth in which the plunger is inserted into the base can switch between a first size and a second size, allowing the user to collect different sample sizes using a single soil sampler. The soil sample that is collected can then be ejected from the soil sampler by shifting the plunger to an eject position relative to the base in which the plunger can shift further into the base to eject the soil sample.

A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

The present disclosure relates to a fluid pump which has a pump casing, a top cap securable to an upper end of the pump casing and having an air intake port and a fluid discharge port. A fluid discharge tube extends to adjacent a lower end of the pump casing. A one-way check valve is disposed adjacent the lower end of the pump and forms a one-way path to admit fluid into the pump casing during a fill cycle of operation of the pump. A one-way check valve at the discharge port allows fluid to escape during a discharge cycle. An auger element is disposed inside the pump casing for causing a swirling, rotational fluid flow during a fluid eject cycle, in response to a jet of compressed air released into the pump casing, in which fluid having collected within the pump casing is forced by the jet of compressed air into and up through the discharge tube, and out from the pump casing.

A handheld computer device is configured to selectively receive a plurality of fluid output values from a paint sprayer and configured to operate in an accessible mode in which the handheld computer device is in a first location where wireless connectivity, via a continuous or near continuous communication path, to at least one of a network server or the paint sprayer is accessible or operate in an inaccessible mode in which the handheld computer device is in a second location out of range of the continuous or near continuous communication path to at least one of the network server or the paint sprayer.

A mix chamber for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mix chamber includes a chamber body extending between a first end and a second end and including flat lateral sides. A ramp feature is disposed proximate the first end and is configured to contact and push first and second side seals, respectively, away from a body axis as the mix chamber shifts in a first direction through a cartridge bore to increase a gap between the first side seal and the second side seal such that the first side seal engages the first flat lateral side and the second side seal engages the second flat lateral side.

A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.

Operator interface device and distributed control for fluid dispensing systems

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network. The remote monitoring system comprises a data storage server, and an end user interface. The data storage server is configured to receive and archive the reports. The end user interface is configured to provide a graphical user interface based on the reports. The graphical user interface illustrates a status of the fluid handling system, sensed and commanded temperatures of the fluid handling system, sensed and commanded pressures of the fluid handling system, and usage statistics of the fluid handling system.
