The price of our pumps and related assemblies are subject to change and are always custom quoted based on your needs and desired quantity, but we do have the following price list with the suggested retail price for our various products.
Pumptec pumps do not require oil, but they require grease. It is not necessary to remove a pump to simply add grease, but it is necessary to install the correct amount of grease when making repairs.
The proper amount can be installed by filling the corners of the plunger slot and a shot of the same amount in the plunger center. Do not fill the plunger slot with grease because it is wasteful and has the potential to create a mess after operating for a period of time.
For more details please refer to TECHNICAL BULLETIN 004:SUPERLUBE MULTI-PURPOSE GREASE.
For cam and plunger-slot lubrication, Pumptec uses Super Lube® Multi-Purpose synthetic grease with PTFE. Use of other types of grease can adversely affect plunger and bearing life.

Problematic inlet conditions
Inlet hoses can become pinched, collapsed or develop tiny holes and affect pump performance. A pinched or collapsed hose will starve the pump and can lead to pulsing as the pump tries to pull enough fluid in. Plumbing connections can lose their seal and permit air to enter the fluid stream. When this air enters the pump, the tiny explosions can create pulses or vibrations in the fluid stream.
Pump valves are stuck or damaged
When a pump valve cannot close completely an imbalance is created and results in pulsation. The valve can have broken part, damaged or debris to prevent complete closure. It will be necessary to examine the pump valves for broken springs, chipped discs or cracked seats. Replace with new valves if any damage is found.
If debris enters the pump, then clean out the debris and examine valve disc and seat for damage. It may be necessary to replace valves.
Rigid outlet plumbing
Due to the pulsing flow that comes from a plunger pump, a soft discharge or pulse hose needs to be used in all systems. If a plunger pump is plumbed with rigid inlet and outlet plumbing, the pulsing shocks can create vibrations and erratic performance.
Faulty regulating valve
An unloader that has an internal seal leak can shuttle or cycle under pressure. Replacement is recommended for all unloader valves instead of repair.
Undersized bypass hose
If the bypass hose from the regulator is undersized, the restriction in the bypass line can make the valve hydraulically unstable resulting in the piston bouncing during bypass. Use one common size larger hose on the bypass line than the port size.
A noisy pump can be the result of several sources including plunger wear, inlet plumbing and incorrect repair.
If a pump has lost the lubricating grease in the plunger slot from lack of preventative maintenance, water splashing the pump or dirty environment, the pump can become loud and should be serviced immediately.
Inlet plumbing can develop air leaks that create very loud noise in the pump. It is the same as cavitation and will destroy the pump if not corrected. It is important to check all connections regularly to verify seal.
Chemical compatibility is crucial to the function and life of our pumps. Use the link below to find the proper elastomer for the chemicals you are using. If the chemical you use is incompatible with Buran or Viton please contact us for further assistance info@pumptec.com or call 763-433-0303 for technical support.

Yes. Both series use the same plunger & seal kit and valve kit. The primary difference between the 205V and 207V is porting within the pump for increased priming capability.

A cam bearing can go bad from over use, lack of lubrication and over pressure.
Bearings have a finite life and will eventually wear out from impacting the plunger over time. Following a preventive maintenance schedule will provide insurance against failure.
In some environments, like hot, humid and dusty, the bearing loses its lubrication and will fail prematurely, so it is important to monitor the level of grease in the plunger slot. It is recommended to perform a grease service every 250 hours in these environments. Additionally, if plunger seals are worn, the leakage can affect the grease to point it cannot lubricate properly any longer. Follow standard preventative service intervals to avoid this problem.
Over pressurization of pump will create excessive stress on the bearing and may result in failure. Maintain rated pressure to prolong the life of pump bearing.
