Frequently Asked Questions | HJ-302007-3
1. What is HJ Waterjet part number HJ-302007-3?
HJ-302007-3 is a direct replacement for H2O 302007-3 Hi-Load Hydraulic Seal Kit, 60K PSI, designed for the hydraulic side of H2O Jet intensifier pumps.
2. What pressure is HJ-302007-3 rated for?
It is the 60K PSI (4,137 bar) version. The corresponding 40K PSI Hi-Load hydraulic seal kit is HJ-302007-5.
3. Where is HJ-302007-3 used?
It is used in the hydraulic section of H2O Jet 40K/60K intensifier pumps, specifically with the Hi-Load piston/hydraulic assembly. It Is listed as the 60K hydraulic seal kit.
4. What does the HJ-302007-3 seal kit do?
The kit maintains the hydraulic seal between the piston and cylinder, helping prevent hydraulic-fluid leakage and maintain the hydraulic force needed to drive the intensifier.
5. Is HJ-302007-3 a high-pressure water seal kit?
No. It is a hydraulic-side/low-pressure seal kit. It should not be confused with the high-pressure seal kit, such as H2O 302004-1 used on the 60K PSI water side.
6. What other parts are commonly replaced at the same time?
Depending on pump condition, technicians may also inspect or replace the Hi-Load Piston Assembly HJ-301023-1, Piston Seal Kit HJ-302013-1, Check-Valve Repair Kit HJ-302003-2, and 60K HP Seal Kit HJ-302004-1.
7. What are the signs that the hydraulic seals need replacement?
Common indications include hydraulic oil leakage, declining pump performance, excessive hydraulic-fluid consumption, inconsistent intensifier cycling, or reduced pressure stability.
8. Can HJ-302007-3 be used on a 40K PSI pump?
No. For the Hi-Load configuration, HJ-302007-3 is the 60K PSI version. HJ-302007-5 is for 40K PSI applications.
9. Is HJ-302007-3 part of a complete pump maintenance kit?
Yes. HJ-302022-1 60K maintenance kit lists HJ-302007-3 as the hydraulic seal kit along with other maintenance components.
