Menjalnice so sestavljene iz štirih jedrnih komponent: 1. prestave (spur ali spiralne). Spur gears are suitable for low-speed, low-pressure applications (resulting in higher noise levels), while helical gears are suitable for high-speed, high-pressure applications (reducing noise levels by over 50%). 2. Pump body and cover (cast iron/cast steel), providing structural support and integrated inlet in izhodiščne cevovodne povezave, s tlačno toleranco 10 - 20 MPa . 3. pogonske gredi (visoko trdno jeklo), s torzijsko trdnostjo večje ali enake 500 n · m, ki neposredno vpliva na življenjsko dobo naprave (tipično 30.000-50 ure) {15}, {15}, {15}, {15}, {15}, {15}, {15}<0.1 ml/min, meeting the explosion-proof requirements of the petrochemical industry. This structural design enables pumps to achieve volumetric efficiencies exceeding 95% in applications such as crude oil transportation and chemical media transfer.
